What happened: Patriots left tackle Will Campbell is out for the remainder of Sunday's game against the Raiders with a right knee injury. He was hurt on a second-quarter run play when Rhamondre Stevenson was brought down on his right leg. Campbell went to the locker room, returned to the sideline to test the knee, and did not come back out after halftime.

Why it matters: Campbell missed time last season with an MCL sprain to the same right knee. First-round rookie Caleb Lomu, taken 28th overall in April, replaced him at left tackle.

What to watch: Watch for any update on Campbell's status once the Patriots finish the game.
