Michael Bennett has been ruled out for the Seattle Seahawks' Week 8 game against the Saints.
Bennett suffered the injury two weeks ago against the Falcons.
The Seahawks will make a determination next week if Bennett needs surgery. It's an unexpected development after Bennett played through the injury in last week's 6-6 tie with the Cardinals.
Bennett hasn't missed a game since joining the Seahawks in 2013.
Bennett's knee injury was the result of a cut block by Falcons left tackle Jake Matthews, a tactic the pass rusher railed against after the game, saying: "To me it's a scary (expletive) move," Bennett said. "Honestly, I think if you dive at someone else's legs, you're a little (expletive). If you are big in the NFL, you just line up and play -- why you got to cut someone on the (expletive) play? I mean, I don't know. That (expletive) is just stupid to me."
