EAST RUTHERFORD -- Expect more musical chairs on the Giants' offensive line.
Center Weston Richburg (concussion) has been ruled out for Sunday's battle of winless clubs against the Chargers, and starting guard John Jerry is questionable after suffering a hamstring injury in Thursday's practice.
"The back of his hamstring tightened up on him a little bit," McAdoo said.
Brett Jones is expected to start at center in Richburg's place. If Jerry cannot play, the Giants will likely put Bobby Hart back at right tackle, move Justin Pugh back to left guard and give D.
