Gardeck (knee) will be placed on injured reserve, Josh Weinfuss of ESPN.com reports.

EDGE Analysis

There was optimism that Gardeck could return this week after being carted off the field last Sunday during a win over the Eagles, but it turns out that he has suffered a season-ending knee injury. It's a tough blow for the third-year pro, who has enjoyed a breakthrough campaign with seven sacks -- including five over his last three games. Markus Golden could receive more snaps with Gardeck sidelined.
