Quinn, the 14th pick out of North Carolina, had to wait five days after changing agents before signing. He missed the first day of training camp on Saturday but is expected to be on the field Sunday.
Coach Steve Spagnuolo said after the first workout that Quinn's plane had landed in St. Louis and that the two had spoken by telephone. Spagnuolo added that Quinn hadn't signed earlier because of a personal issue, not a contract issue.
"Now it's physicals and the contract. Hopefully that won't be a problem," Spagnuolo said. "We'll get him out there just as soon as the league says we can do it."
Quinn had 11 sacks as a sophomore, but was among three players kicked off the team last year for receiving improper benefits, and then was declared permanently ineligible.
Spagnuolo said the Rams were attempting to restructure contracts with offensive guard Jacob Bell and defensive back James Butler, and were hopeful both could remain with the team. Both were on the sidelines watching practice.
Spagnuolo said he'd like to re-sign offensive guard Adam Goldberg, an unrestricted free agent.
The Rams have agreed with former Broncos and Ravens defensive tackle Justin Bannan on a three-year deal. He rejoins Josh McDaniels, his coach at Denver who is now the offensive coordinator in St. Louis.
Bengals sign QBs Dalton, Gradkowski
Dalton was a second-round draft pick from TCU. Owner Mike Brown said at the start of camp that he thinks Dalton can handle the job, even though there will be some growing pains. Gradkowski can't practice until next week when the new labor agreement is completed. They also have Jordan Palmer, who was the No. 2 quarterback last year.
Gradkowski, formerly of the Oakland Raiders, got a two-year deal, which he agreed to Wednesday.
Dalton will get the first crack at the starting job. The red-haired rookie lined up with the offense for the first drill on Saturday night, threw a pair of dump-off passes to running back Chris Pressley, then had a short completion to Green.
Offensive coordinator Jay Gruden liked what he saw in the first practice, but was more focused on how much more the players have to learn in his new offense.
"This is like freshman PE (physical education) and this is your first class in high school," Gruden said. "You still have a long way to go in high school and college and medical school. We have a long way to go to get to where we want."
The Bengals also signed linebacker Dontay Moch, their third-round pick. All eight of their draft choices were under contract before the first practice.
However, the Bengals may have lost linebacker Roddrick Muckelroy for the season after he says he ruptured an Achilles' tendon during the first practice of training camp and will be out for the season.
Vikings sign wide receiver Jenkins
Atlanta drafted the 6-foot-4, 217-pound Jenkins 29th overall in 2004. Jenkins never lived up this first-round billing, with 20 touchdowns in seven NFL seasons.
Titans re-sign Harris, agree to Ruud deal
The 28-year-old Ruud has led the Buccaneers in tackles the past three years.
Ruud was responsible for making the calls as the middle linebacker for the team's defense, stepping into the role after the Bucs ended ties with longtime star Derrick Brooks.
The Titans also will be returning their starting offensive line intact after left guard Leroy Harris signed Saturday.
Harris' agent, Hadley Engelhard, confirmed Saturday that the left guard agreed on a two-year deal. The Titans had wanted to bring the 6-foot-3, 303-pound guard back because of his versatility to play both center and guard. Harris started all of 2010 for Tennessee at left guard.
Coach Mike Munchak said after practice he knows the other coaches will be happy to have Harris back, even though he won't be able to practice with the Titans until Thursday when veterans freshly signed can finally work with the team.
"That would've been a big problem if we didn't get him signed," Munchak said.
The Titans had a practice Saturday morning indoors with no helmets that was closed to reporters and another practice with helmets outside in the afternoon. The Titans held receiver Kenny Britt out of the afternoon session, and Munchak said they are trying to be careful with players who have a history of hamstring injuries like Britt.
Packers re-sign three
Crosby, a sixth-round draft choice of the Packers in 2007, got a five-year deal. Havner was placed on the injured reserve in November because of a hamstring injury,
Swain, a special teams player, appeared in all 16 games, with one start, last season and had six catches for 72 yards, in addition to seven tackles on special teams. He also tied for the team lead in the postseason with an additional seven stops on special teams.
Ravens, Carr agree; Ngata wants longer deal
Unrestricted free agent cornerback Chris Carr has signed a four-year contract to stay with the team.
Carr says there were "numerous teams" interested in signing him, and that he "almost did leave." But he wanted to remain in Baltimore because "you want to be a place where you're happy and winning."
Carr started in all 16 games with the Ravens last season as a fill-in for the injured Domonique Foxworth. He finished with two interceptions, 56 tackles and forced three fumbles.
Meanwhile, All-Pro defensive tackle Haloti Ngata signed his franchise tag, but that doesn't mean he's content with the one-year payday.
Ngata, who lost 20 pounds during the offseason, says he doesn't mind being Baltimore's franchise player, but wants more money over a longer period of time. He says "that's what I am really trying to shoot for."
"I lost the weight basically just to see how I felt during the season and see how it would affect me towards the end of the season," Ngata said. "I felt like last year I was kind of getting a little worn down just having so much weight on, and I just wanted to see how it felt this year."
His next objective is to shed the franchise tag the Ravens foisted upon him in February.
"As long as I can get that long-term contract, that's what I am really trying to shoot for," Ngata said.
The 27-year-old Ngata had 65 tackles last year and ranked second on the team with a career-high 5½ sacks. He was named to the AP All-Pro team and earned a second straight Pro Bowl berth.
Falcons welcome new DE Edwards, sign Bryant
Enter Ray Edwards.
The Falcons' welcomed their new defensive end to training camp Saturday and can't wait to get him out on the field alongside John Abraham, who essentially had to go it alone last season when it came to rushing the passer.
Atlanta ranked 20th in the league last season with just 31 sacks -- and Abraham had 13 of those. The other end, Kroy Biermann, managed only three.
Edwards should be a major upgrade, totaling 16.5 sacks the last two years with the Minnesota Vikings. He agreed to a five-year, $30-million contract with the Falcons that includes a guarantee of $11 million.
"I think me and Abraham are definitely going to be a great tandem," Edwards said after watching an afternoon practice from the sideline, decked out in a new red-and-black Falcons cap. "We'll work on playing off each other and causing a lot of havoc."
The Falcons also re-signed kicker Matt Bryant to a four-year contract.
The 10-year veteran made 28 of 31 field-goal attempts last season, including three game-winning kicks. He joined the Falcons late in the 2009 season after Jason Elam was released.
Atlanta announced that three restricted free agents -- Pro Bowl returner Eric Weems, backup defensive tackle Vance Walker and third-string quarterback John Parker Wilson -- signed their one-year tenders.
DBs Landry, Coleman sign Jaguars contracts
The team also signed defensive end Steven Wesley to the roster and waived offensive lineman Sifa Etu on Saturday.
The Jaguars now have 91 players under contract, but holdout tight end Marcedes Lewis does not count against the 90-man limit because he's on the reserve/did not report list.
Landry spent the past five seasons with Baltimore, starting 64 games and recording 387 tackles and nine interceptions. Coleman played in 67 games during five seasons with the New York Jets. He had 34 tackles, four sacks, five forced fumbles and an interception last season.
Raiders sign OL Barnes, QB Edwards
Edwards, a third-round draft pick in 2007 out of Stanford, opened the 2010 season as Buffalo's starter but was benched and released after two games. The Jaguars claimed him off waivers in late September. The 27-year-old Edwards has passed for 6,019 yards and 26 touchdowns in his career while throwing 30 interceptions and getting sacked 69 times.
"He has some characteristics that I look for in a quarterback," Raiders coach Hue Jackson said. "Having an opportunity to sit down and talk to him, he was what I was looking for. I mean, he's a big, strong, physical guy that can throw the ball. Loves football. Very passionate about the game. He's a gym rat. He likes to go in and study from morning to night. It's important to him. He's looking for an opportunity and we're a place that has an opportunity."
The Raiders considered drafting Edwards in the later rounds in 2007, but ended up taking JaMarcus Russell first overall instead. Russell lasted just three seasons in Oakland before being cut last year. Now Edwards gets his chance.
Browns sign Dawson, seven draft picks
Unrestricted free agents Brandon Jackson, a running back from Green Bay and defensive back Usama Young of New Orleans also were among the signings announced Saturday before coach Pat Shurmur held his long-awaited first practice.
Signing tenders were Dawson as a franchise player, tight end Evan Moore as a restricted free agent and linebacker Marcus Benard and defensive lineman Brian Schaefering as rights players. Offensive lineman Billy Yates also re-signed.
The only unsigned draft pick remaining is No. 1 Phil Taylor, a defensive lineman from Baylor.
Dolphins sign Pouncey, Burnett
Crowder, a six-year starter for Miami, was released Friday following the first practice of training camp to pave the way for Burnett's acquisition.
Burnett played for San Diego the past two seasons. He started seven games in 2009 and all 16 games last year, when he had 80 tackles, six sacks and two interceptions.
Burnett will earn $20 million over four years, a source told ESPN.com senior NFL writer John Clayton.
The Dolphins' first-round draft choice Mike Pouncey also signed a contract after missing the first two days of practice in training camp.
With the signing Saturday, all of the Dolphins' draft picks are under contract.
Pouncey, projected to start at center for Miami, started 45 games for Florida and was the 15th overall pick in the draft. His twin brother, Maurkice, made the Pro Bowl as a rookie center for the Pittsburgh Steelers last season.
A second-round draft pick by the Dallas Cowboys in 2005, Burnett spent four seasons with them.
"I have a good history with Kevin," said Miami coach Tony Sparano, a former Cowboys assistant coach. "I was there with him in Dallas when we drafted him. This is a guy who can play on all three downs and runs really well and can cover some of the bigger tight ends and bigger backs in our league."
Replacing Crowder with Burnett gives the Dolphins more flexibility and better pass coverage, Sparano said.
Cardinals agree with Marshall, sign Evans
The fifth-year player started all 32 games with the Carolina Panthers the past two seasons. Marshall has never missed a game in his NFL career.
Arizona also announced Saturday it signed undrafted free agent rookie cornerback Tae Evans.
Faulk stays with Patriots
New England re-signed veteran running back Kevin Faulk, an unrestricted free agent who appeared in two games for the Patriots last season before tearing the ACL in his right knee and sitting out the rest of the year.
The 35-year-old Faulk has spent his entire 12-year career with the Patriots after being drafted by the team in the second round (46th overall) of the 1999 draft. He is currently the longest-tenured Patriot on the roster.
Offensive lineman Logan Mankins signed his franchise tender; unrestricted free-agent running back Sammy Morris and restricted free-agent defensive back Kyle Arrington re-signed with the team; and defensive lineman Steve Williams came to terms with the club.
Lions introduce free-agent additions
The Lions ranked 24th in the NFL against the run last season and allowed opponents almost 125 yards per game on the ground. Durant, who started nine of the 10 games he played last season in Jacksonville, had 55 tackles. His best was the previous season, when he started 13 games and registered 98 stops with an interception.
The four-year veteran immediately upgrades a linebacking corps that relied heavily on DeAndre Levy to be its lone playmaker last season.
Wright adds a starter's swagger to a secondary that struggled to replace injured players most of last season. He had just one interception last season and swiped four while starting all 16 games in 2009.
Chargers, backup QB Volek agree to 2-year deal
The Chargers and backup quarterback Billy Volek have agreed to a two-year contract Saturday.
Volek, 35, enters his sixth season with the club. He hasn't started for the Chargers, but after Philip Rivers was hurt against the Colts in the 2008 Divisional Playoffs, Volek replaced him and led the Chargers to the victory at Indianapolis.
Volek started 10 games for the Titans from 2003-05 and has a career passer rating of 84.9.
Chiefs get Gregg
The Kansas City Chiefs signed free-agent nose guard Kelly Gregg, a 12-year veteran who was released by the Ravens because of money. Gregg, 34, considered a solid and gritty presence, has played a career 138 regular-season games (123 starts) and is a proven commodity.
