Rookie quarterback Mitchell Trubisky had a spectacular debut for the Bears, completing his first 10 passes against the Broncos. Elsewhere, the projected starter at middle linebacker for the Dolphins was injured.
NFL Nation reporters recap the day, bringing you what you need to know from training camps and preseason games across the league:
FINAL: Broncos 24, Bears 17. The Broncos rookies -- quarterback Kyle Sloter, Isaiah McKenzie and running back De'Angelo Henderson powered a 14-point fourth for the Broncos to get the win. Sloter hit McKenzie for a 47-yard touchdown pass after the Bears busted a coverage to tie the game and Henderson then scored the game-winner with a 41-yard run.
The Broncos scored a late touchdown to beat the Bears 24-17........but who cares, the night belonged to Mitchell Trubisky. The Bears rookie quarterback led Chicago to three consecutive scoring drives and finished 18-for-25 for 166 yards and one touchdown pass to veteran receiver Victor Cruz. The Bears aren't going to change quarterbacks -- Mike Glennon had a terrible night with a pick-6 -- but Trubisky will continue to be the most talked about football player in Chicago.
The only positive development so far for the Bears is that former first round pick Leonard Floyd recorded a sack. Floyd had seven sacks as a rookie.
Overheard at camp: "Jimmy's really healthy right now." Russell Wilson talks about what he's seeing from Seahawks TE Jimmy Graham at training camp.
Biggest takeaways: The Falcons looked sharp on both sides of the ball with their first team offenses and defenses in a 23-20 exhibition loss to Miami. And newcomer Andre Roberts made an immediate impact in the return game. But there will be a lot of conversation about CB Jalen Collins, the second-round draft pick who was recently suspended without pay for the first 10 games of the regular season for again violating the league's policy on performance-enhancing substances. Collins, who is allowed to practice now and play in the preseason, got beat for a 99-yard TD late and made a few other mistakes. You wonder if the Falcons will cut ties with Collins and allow another cornerback to emerge to provide depth.
Rookie Raekwon McMillan, who was projected to start at middle linebacker, suffered a knee injury on punt coverage in the opening moments of the Dolphins preseason win against to the Falcons. McMillan left the Miami Dolphins locker room on crutches with a brace on his right knee. Behind him at middle linebacker is Mike Hull, an undrafted player with one career start in his first two seasons.
Final score: Vikings 17, Bills 10: Minnesota's heralded defense set the tone early, finished with three sacks and a number of pressures. Offense had some hiccups, although Stacy Coley had 3 catches for 67 yards.
The Bills dropped their preseason opener, 17-10, to the Vikings on Thursday night. RB LeSean McCoy dressed but did not play, while QB Tyrod Taylor played the first three offensive possessions. Taylor dodged injury on a sack after which he came up gimpy and was evaluated by trainers on the sideline. He returned for the next series.
Play of the day at camp: Dez Bryant retired this award today by jumping over Orlando Scandrick to make a one-handed, lefthanded grab of a Dak Prescott fade for a touchdown. Bryant playfully tossed the ball back at Scandrick and then did a chest bump with left tackle Emmett Cleary. Bryant leaped as high on the chest bump as he did for the touchdown catch.

Leonard Fournette had a solid debut for the Jacksonville Jaguars in their 31-24 victory over New England on Thursday night. The rookie ran for 31 yards and a TD and showed off his power between the tackles as well as a surprising spin move. Granted, the Patriots did not play a single starter on either side of the ball, but the important thing was that Fournette did what he was supposed to do on his nine carries. The fourth overall pick's next test is two days of joint practices with Tampa Bay on Monday and Tuesday.
Of the two primary storylines from the Patriots' preseason opener, one came on the field (Jimmy Garoppolo) and the other came off the field (Roger Goodell). Garoppolo was excellent despite playing without almost all of the team's top skill-position players, while Goodell showed up at the game and said hello to owners Robert Kraft and Shad Khan before leaving by halftime. It was Goodell's first visit to Gillette Stadium since the playoffs following the 2014 season. Goodell plans to return for the NFL opener.
Jets DL Leonard Williams likes what he sees from the defensive line, easily the most talented position group on the team.
The Saints lost their 10th straight preseason game when they couldn't hold on to a late lead against the Browns and rookie QB DeShone Kizer. But there were still reasons for encouragement in the 20-14 loss, which saw stars like Drew Brees, Adrian Peterson, Mark Ingram and Cameron Jordan taking the night off. Rookie running back Alvin Kamara started the game with two explosive runs on the first two series (a 12-yarder and 22-yarder). And the Saints' embattled defense forced three straight 3-and-outs to start the game when the starters were in. Safety Kenny Vaccaro, edge rusher Hau'oli Kikaha, cornerback P.J. Williams and defensive tackle David Onyemata were among those with multiple highlights.
Let the discussion resume: DeShone Kizer threw a game-winning 45-yard touchdown pass with 1:52 left as the Browns beat New Orleans 20-14 in the preseason opener. Kizer also had a 52-yard throw, and 184 yards passing in the second half. He faced backups and third-teamers, but the rookie from Notre Dame took full advantage of a huge opportunity provided by coach Hue Jackson.
The Redskins lost the preseason opener, 23-3, to the Baltimore Ravens in a game that featured poor offensive play much of the night. The Redskins managed just eight first downs and 138 total yards with no points by the first or second offenses. The blocking in both the run and pass game was not to the level Washington will need if it wants to contend for the NFC East title this season.
Ravens defense dominated the Redskins' first-team offense up front. Baltimore forced Kirk Cousins into three-and-outs on only two drives of the night, holding Washington to minus-one yard on six plays.
Ravens 23, Redskins 3: The preseason opener resembled what's been happening in training camp. Ryan Mallett struggled to hit receivers, finishing 9 of 18 for 58 yards (57.2 passer rating) in one half of work. Baltimore's defense looked just as strong as it has all summer, dominating Kirk Cousins and the Redskins first-team defense.
Eagles first-round pick Derek Barnett is having a very strong debut. He has a pair of sacks in the first half against the Packers. On the first one, he put a nice inside move on tackle Jason Spriggs before tracking down QB Brett Hundley.
The Steelers are applying more public pressure on Le'Veon Bell sitting out camp. It started July 27 with coach Mike Tomlin saying there could be untold 'consequences' with Bell missing significant time, and now GM Kevin Colbert tells the Pittsburgh Post-Gazette that Bell has nothing to gain from his absence. That likely won't change Bell's plan. Signs point to a mid-to-late-August return to the team.
A change at quarterback? No, it's not time for quarterback Andrew Luck to return yet. And coach Chuck Pagano has already said Scott Tolzien will start at quarterback against the Lions in the preseason opener on Sunday afternoon at Lucas Oil Stadium.
But there could be changes when it comes to who backs Tolzien up. Undrafted rookie Phillip Walker out of Temple has appeared to move ahead of Stephen Morris, who is in his third season with the team, on the quarterback depth chart, as he's been getting the bulk of the snaps with the second unit.
The Colts say they haven't determined the rotation behind Tolzien on Sunday, but Pagano did acknowledge that Walker has seen increased snaps.
"He's done a nice job and he's performed well," Pagano said. "We're taking a really good look at him."
Raiders Rookie Report: First-round draft pick Gareon Conley disputed on Twitter GM Reggie McKenzie's claim that the cornerback was suffering from shin splints. "I don't have shin splints lol," Conley Tweeted. Conley, who was accused of rape but charges were never filed, has yet to practice with Oakland. He signed his rookie contract the day before training camp began.
Derek Carr is a draw for the crowd before Raiders practice here in Napa on Thursday.
Lions coach Jim Caldwell told reporters in Indianapolis that RT Rick Wagner suffered an injury during joint practices with the Colts, but called it "a little issue," according to the Detroit Free Press. If he's out for any length of time, that would knock out both of Detroit's starting tackles, Wagner and Taylor Decker. Detroit has had offensive line injury issues all camp long.
