The Packers offensive line will receive some reinforcement for this weekend’s game against the Colts. According to NFL.com’s Mike Garafolo (via Twitter), the team has activated center Corey Linsley from 
the physically unable to perform list. ESPN’s Rob Demovsky tweets that the 25-year-old will start for the Packers tomorrow.
Linsley, a fifth-round pick in 2014, has spent his entire three-year career with the Packers, and the 25-year-old has started all of his 29 NFL appearances. As a rookie, Linsley filled in for an injured J.C. Tretter at center, and the lineman didn’t relinquish the job over the next two season. The lineman was placed on the PUP in early September after tearing his hamstring twice.
Tretter had done an admirable job filling in for Linsley, as the 25-year-old ranks as the league’s fifth-best center according to Pro Football Focus’ advanced metrics (subscription required). The Packers offensive line has also allowed the fewest rushing yards in the league, although they’ve allowed a mediocre 19 sacks through seven games.
