The Packers have made a pair of transactions involving centers, according to Rob Demovsky of ESPN.com, who reports (via Twitter) that the team has placed J.C. Tretter on injured reserve with the designation to return. In his place, Green Bay has promoted Garth Gerhart from the practice squad to the active roster.
Tretter, who missed his rookie season last year, with leg and ankle injuries, was sidelined during the preseason with a knee injury, and had been viewed for the last week or so as the top candidate for Green Bay’s IR-DTR spot. In his absence, rookie Corey Linsley is expected to start for the Packers at center.
The Packers now have an opening on their practice squad, which they’ll likely fill in the near future. Additionally, Green Bay becomes the 10th NFL team to use its IR-DTR spot.
