The Tennessee Titans have placed edge rusher Jadeveon Clowney on injured reserve and will miss at least three games.
Clowney (knee) had already been ruled out for Sunday's game versus the Ravens after missing practice all week.
NFL Network's Mike Garafolo added that surgery on Clowney's meniscus has been discussed.
Clowney has yet to find a sack in his first season with the Titans. In eight games, the three-time Pro Bowler has 19 total tackles, four tackles for loss, a forced fumble and six QB hits. Clowney signed a one-year deal with Tennessee worth up to $15 million this offseason.
The Titans also placed cornerback Kareem Orr (groin) on IR. Orr was listed as questionable vs. the Ravens. In corresponding moves, the team elevated linebackers Will Compton and Tuzar Skipper to the game day roster. Both will revert back to the practice squad following Sunday's game. Defensive back Greg Mabin was also elevated from the practice squad to the active roster.
