The Carolina Panthers offensive line has been shuffled around for the past two weeks and it appears that will continue. Starting right guard Garry Williams left Sunday’s game in the first half with a left knee injury and after the game Ron Rivera wasn’t optimistic about a timely recovery. The Panthers are already down a starting left guard in Amini Silatolu and they played guard by committee Sunday. Rivera is hopeful Silatolu will be back from his hamstring injury in time for next week’s game at Buffalo. “It’s not looking good for Garry Williams right now” Rivera said. “We will get an MRI on that to see exactly the extent but we most certainly need those guys back next week.” Chris Scott got the start at left guard and alternated with Travelle Wharton. The Panthers signed Scott midway through training camp and signed Wharton two weeks ago. Wharton a 10-year veteran spent his first eight years at Carolina. Left tackle Jordan Gross and center Ryan Kalil are the only linemen entrenched at their positions. Gross said he believed the players at left guard played well. But with Williams out the Panthers will likely slide Scott over to right guard. That would leave Carolina with just one backup — Jeff Byers — on the interior of the line.
