After Tuesday's practice, Green Bay Packers coach Mike McCarthy said Tretter would miss the rest of organized team activities. More likely, the fourth-round pick out of Cornell will spend his rookie season on injured reserve. It's typically a six-month recovery time, with Tretter being unable to put any weight on the injury for the first three months after surgery.
However, a return is not out of the question. One of the players represented by Fox and Alan Herman of SportStars, Cincinnati center Kyle Cook, sustained a similar injury during the Aug. 23 preseason game against Green Bay. Cook wound up playing in four games, including making two starts.
The difference is Cook is a veteran who had started all 48 games the previous three seasons. Tretter is a rookie who will have missed the offseason practices and training camp by the time he's healthy.
During a routine fumble recovery drill in which the linemen slide baseball-style while securing the ball, Tretter had a cleat get stuck in the Clarke Hinkle Field turf, breaking his fibula and tearing ligaments.
For a team that values versatility and the ability to have only seven linemen active on game day, Tretter is a significant loss because he had the ability to play guard, center and perhaps both tackle spots. Tretter presumably would have made the 53-man roster, so that improves the odds for the likes of Marshall Newhouse, Don Barclay, Andrew Datko, Greg Van Roten and rookie free agents Lane Taylor and Patrick Lewis.
Not participating (but on the practice field) were rookie receivers Kevin Dorsey and Charles Johnson, running back DuJuan Harris, safety Sean Richardson, cornerback Davon House, linebackers Dezman Moses and Desmond Bishop, offensive tackle Derek Sherrod, and defensive linemen Ryan Pickett and Jerel Worthy.
McCarthy would not discuss injuries, though he did say Bishop (missed last season with hamstring), House (shoulder) and Sherrod (missed last season with broken leg) would likely return in that order.
Cornerback Sam Shields was absent. He has not signed his restricted free agent tender.
"Sam Shields is a young player and our program speaks for itself and how young players develop year to year," McCarthy said. "I wish Sam was here. He's not here for his specific reasons that I'm sure if he wants to answer them, he can answer them. It's about the opportunity to compete and our secondary is very competitive. I wish he was here."
Back in action after missing all of last season was tight end Andrew Quarless.
— A few highlights: There were a few scuffles, including two involving first-round pick Datone Jones. ... Jarrett Bush had an interception and broke up another pass. ... Nick Perry, who missed much of last season with wrist and knee injuries, blew past David Bakhtiari for a sack. ... Barclay, getting some work at center, and quarterback B.J. Coleman botched a snap. ... Rookie running back Johnathan Franklin stopped blitzing Mike Neal.
— Donald Driver joined the Packers in 1999 and Charles Woodson signed with the team in 2006. Driver has retired and Woodson has been released, leaving a leadership void. "It's going to be tough to replace guys like that," quarterback Aaron Rodgers said. "The leadership areas you miss the most. Obviously, from a friendship standpoint, it was great to spend so many years with them and be a part of so many great victories and accomplishments, and watch them achieve incredible individual success and be able to play with them and achieve some team success as well. We'll miss them a lot. Those guys are incredible players and people."
— McCarthy, on practice: "I thought today was kind of typical of the first time the team takes the field. It was a little disjointed. The energy was great, the intent was great, but your team has to learn to practice together — like it does every time they get together, and I think you saw some of that today."
— The next practice open to fans and reporters will be at 11:30 a.m. on Tuesday, May 28, also at Clarke Hinkle Field.
