Houston is out for the year after suffering a torn ACL on Sunday, ESPN's Adam Schefter reports. Houston's injury occurred while he was celebrating a sack in the fourth quarter of the Bears' blowout loss to the Patriots on Sunday. The defensive end, who signed a five-year, $35 million deal with the Bears this past March, thus concludes his 2014 campaign with 11 tackles and one (costly) sack in eight games.
