The Green Bay Packers will practice again Saturday, but so far JC Tretter has made it through his first week back without any setbacks.
The second-year offensive lineman was slated to be the team's new starting center before a knee injury during the preseason landed him on temporary injured reserve. He's eligible to be activated following next week's game in New Orleans, but he passed his first test in practice.
Rookie Corey Linsley has made a convincing argument to remain in the starting lineup even after Tretter returns to full form. Based on his history as a two-year starting left tackle at Cornell, the Packers have confidence Tretter can play multiple spots on the line.
"I think JC has the ability to play multiple positions, no doubt about it," McCarthy said. "He actually took reps at multiple positions today in the opponent squad. We're trying to give JC as much work as we possibly can."
• Miami receiver Jarvis Landry was fined $8,268 for grabbing the face mask of Packers cornerback Casey Hayward following his second-quarter interception of Dolphins quarterback Ryan Tannehill.
• The Packers re-elected receiver Jordy Nelson as their NFLPA representative with punter Tim Masthay and defensive back Micah Hyde serving as alternates, the players union announced Friday.
Ryan Pickett and Tramon Williams previously served as Nelson's alternates.
