More bad news for Bills' defense

The Buffalo Bills' struggling defense lost one of its big free-agent acquisitions this week. Starting defensive end Mark Anderson will be out "indefinitely," Bills general manager Buddy Nix told the team's website on Wednesday.

Buffalo signed Anderson and fellow defensive end Mario Williams this offseason to improve its pass rush. So far, neither player has produced. The high-paid duo with contracts totaling more than $100 million have combined for just 2.5 sacks in five games. Anderson had 10 sacks last season for the New England Patriots.

The good news is Buffalo has depth at defensive end. The Bills will turn to veteran and former starter Chris Kelsay, who is one of the longest-tenured players on the team. Kelsay has three tackles and zero sacks on the season as a backup.

Buffalo’s defense needs someone to step up. The Bills have allowed 97 points in the past two games, which has drawn the ire of Bills fans, Nix and head coach Chan Gailey.

The Bills (2-3) will play at the Arizona Cardinals (4-1) on Sunday.
