Rhyan exited in the first quarter of Sunday’s game against the Lions after he had his leg rolled up on during the Packers’ fourth offensive play of the game. The 26-year-old lineman did not return to the game and is now looking at a potential four-to-six-week absence. Rhyan has started every game at center for the Packers this season, allowing three sacks and 10 pressures on 394 snaps. He was replaced by John Williams, a tackle, who could be in line to make the start next week given the multiple injuries along the Packers’ offensive line.
