The Buffalo Bills' defense has suffered a resounding blow.
In a one-sentence statement released Thursday night, the Bills announced they've placed LB Angelo Crowell on injured reserve, ending his season. Crowell led the Bills in tackles last year and was a defensive captain.
Crowell was not listed on the Bills' injury report Wednesday, but the Buffalo News is reporting he underwent arthroscopic knee surgery Thursday. BuffaloBills.com is reporting Crowell is scheduled for a knee scope to determine the nature of a nagging injury.
Either way, Crowell's season is over. Keith Ellison, who started at weakside LB last year, will move over to Crowell's strongside position.
The Bills responded to Crowell's surgery decision by placing him on IR. That creates room on their 53-man roster. A knee scope -- if that is, in fact, all there is to Crowell's injury -- normally would take only a few weeks to heal.
Had Crowell given the Bills advance notice he wanted the surgery, they could have placed him on the physically unable-to-perform list. That would have allowed him to return to action after sitting out the first six weeks of the regular season.
The move suggests the Bills' front office wasn't too happy about Crowell's decision a few days before their regular-season opener.
