EAST RUTHERFORD, N.J. - The Giants appear to be bracing for another offensive line shakeup -- and maybe one on the defensive line, too.
Three key players on those lines were missing from the 0-4 team's practice on Wednesday -- center Weston Richburg and defensive ends Olivier Vernon and Jason Pierre-Paul. Richburg is in the NFL's concussion protocol and it seems unlikely he'll be available for the game against the 0-4 Los Angeles Chargers on Sunday. Vernon is dealing with ankle injury and JPP has a shoulder injury that apparently got worse over the last few days.
The JPP injury is a bit of a mystery since he played every snap of the Giants' 25-23 loss in Tampa on Sunday. The Giants actually listed him with both knee and shoulder injuries. Ben McAdoo said the shoulder injury developed over the last two days and his status won't be clear until the team sees how he responds to treatment.
Asked how his shoulder was feeling, JPP said "I'm not talking today." He blew off reporters after the game on Sunday, too.
Vernon, meanwhile, made it through only 22 snaps on Sunday after reaggravating an ankle injury that has bothered him for weeks. He did work with trainers on the side during the Giants practice on Wednesday.
As for Richburg, he left the Giants' loss in Tampa on Sunday after suffering a concussion. In a clear sign that his status is in doubt, the Giants promoted center Jon Halapio from their practice squad. Guard Brett Jones is expected to start at center against the Chargers if Richburg can't go. It's unclear what the rest of the line will look like, though it could return to normal now that right tackle Bobby Hart (ankle) is no longer on the Giants' injury report.
Cornerback Janoris Jenkins also did not practice on Wednesday due to the ankle injury that has bothered him for weeks.
Meanwhile, four Giants were limited at practice: WR Odell Beckham, Jr. (finger/ankle), RB Orleans Darkwa (back), WR Brandon Marshall (toe), and RB Paul Perkins (bruised ribs). DT Damon Harrison, who hurt his knee on Sunday, practiced fully, according to the Giants.
