The move provides San Diego with insurance along the offensive line after the Chargers finished Thursday’s game against Oakland without three of its starters.
Left tackle Marcus McNeill left on a cart after a hard collision and missed snaps due to a neck injury for the second time this season. Kamerion Wimbley made four sacks for the Raiders in his absence. Left guard Kris Dielman (concussion) missed his third-consecutive game last week and Louis Vasquez (ankle) also could not finish last week’s game.
