Green Bay Packers center J.C. Tretter will miss the season opener in Seattle on Sept. 4 and could be out up to six weeks, according to a report.
ESPNWisconsin.com’s Jason Wilde reported Sunday that, according to an NFL source, Tretter was examined during the preseason game Friday against the Oakland Raiders and stayed in the game. But after playing 49 snaps and exiting the game with the rest of the first team, he started having problems.
“Once the ones went out of the game, and once he settled down, that’s when it started bothering him,” coach Mike McCarthy said. “It was bothering him at halftime, then when I got back in here after the game [the medical staff] ended up putting him on crutches.”
Tretter, a fourth-round pick from Cornell in 2013, missed all of last season after breaking his ankle during the first day of organized team activities.
After starting center Evan Dietrich-Smith signed as a free agent with the Tampa Bay Buccaneers last spring, Tretter easily beat out fifth-round pick Corey Linsley and former practice squad center Garth Gerhart for the starting job.
The Packers are already down one offensive lineman as top reserve Don Barcley sustained a season-ending knee injury last week.
The league source told Wilde that Tretter did not sustain any ligament damage, calling the injury similar to a stress fracture.
