What to watch in Week 3 of Packers' OTAs

GREEN BAY, Wis. -- The Green Bay Packers return to work on Tuesday to begin their longest week of organized team activities with four workouts scheduled.

The first two weeks included three sessions each.

Tuesday's practice at 12:30 p.m. ET (11:30 a.m. CT) will be the only one this week open to fans (weather permitting) and reporters.

Here are some things to keep an eye on:

1. Undrafted rookies: It will be another couple of months before we have a solid feel for which undrafted rookies -- if any -- have a real shot to make the roster, but a few of them already have done enough to warrant some early consideration. While players like tight end Colt Lyerla of Oregon and outside linebacker Adrian Hubbard of Alabama have gotten the most publicity so far among the undrafted free agent class, it's worth watching how a few others progress. Among those who have stood out early on are North Carolina State defensive end Carlos Gray and a pair of inside linebackers, Jake Doughty of Utah State and Joe Thomas of South Carolina State.

2. Lyerla's return: Lyerla was excused from at least one of last week's OTA sessions. He was not present when reporters and fans were last allowed to watch last Tuesday, but the controversial rookie tight end was expected to return and should be on the field for this week's sessions. Because of his past troubles and transgressions, just about everything Lyerla does will be scrutinized.

3. Worthy's return: Third-year defensive end Jerel Worthy understandably was absent last week after his grandmother was accidentally shot near Dayton, Ohio. She died a short time later. It's not clear whether Worthy will return this week or not, but the reality of the NFL is that it waits for no one and Worthy has much to prove. He returned late last season from reconstructive knee surgery but so far has not lived up to his billing as a second-round pick in 2012. This is a big offseason for him.

4. Guion's role: Defensive tackle Letroy Guion was almost an after-thought signing in free agency. He received only a one-year deal with a signing bonus of just $100,000, but the former Minnesota Vikings role player is off to a good start with the Packers. Last week, with B.J. Raji absent, the 6-foot-4, 317-pound Guion took some meaningful snaps with the defensive starters.

5. Other receivers: While much of the attention has been on draft picks Davante Adams, Jared Abbrederis and Jeff Janis, there have been some other receivers who have stood out so far in OTAs. Chris Harper, a waiver-claim addition last season, had a strong practice last Tuesday. So did Jarrett Boykin, who at this point remains the No. 3 receiver behind Jordy Nelson and Randall Cobb. Second-year pro Kevin Dorsey, a seventh-round pick who spent all of last season on injured reserve, is healthy again and has shown signs of being productive. So has Myles White, who played some last season when injuries hit.

Note: This is the final week of OTAs. The Packers hold their mandatory minicamp next week. Exact practice times for the June 17-19 camp have not been announced.
