Seahawks coach Pete Carroll said linebacker Bruce Irvin sprained the medial collateral ligament (MCL) in his knee during Sunday night’s loss to Arizona but had no timetable on when he might be able to return, saying, “We’ll see what that means.”

Irvin was injured in the second half and didn’t return to the game.

Wide receiver Paul Richardson sustained the other injury of note for Seattle. Carroll said he may have pulled his hamstring, though he didn’t give any indication as to how long that might sideline him.

Richardson made his season debut, playing for the first time since injuring his knee in last season’s playoffs. His lone catch gained 40 yards and set up Seattle’s first touchdown.

Carroll said wide receiver Tyler Lockett came out of the game with a sore ankle but is OK.
