Lewis (knee) has been ruled out for Thursday's game against the Packers.
Lewis likely picked up the injury during Sunday's 43-13 loss to the Buccaneers. He was unable to practice all week due to his injury, and with Torricelli Simpkins (ankle) also ruled out, Corey Bullock figures to step into the starting role at left guard. Lewis' next chance to play is Week 9 against the Broncos on Sunday, Nov. 8.
