Seattle Seahawks defensive end Michael Bennett will undergo arthroscopic knee surgery this week to repair cartilage and is expected to be out two to three weeks, a source told ESPN NFL Insider Adam Schefter.
The Seahawks had already ruled out Bennett for Sunday's matchup against the New Orleans Saints.
Bennett initially injured his right knee in Week 6 against the Atlanta Falcons, but he played 81 snaps in Week 7 against the Arizona Cardinals. Seahawks coach Pete Carroll said the latest injury "might be related" to the issue that surfaced against the Falcons.
"There was a little something we found in the MRI, so we're going to make sure we know what we're doing and take good care of him," Carroll said Friday.
Bennett has been one of the Seahawks' most disruptive defensive linemen with three sacks and a team-high four tackles for loss this season. Second-year player Frank Clark (4.5 sacks) will likely replace him.
