Really tough news for the Arizona Cardinals as they’ve lost yet another big player.

The Arizona Cardinals have confirmed the seriousness of the knee injury defensive tackle Darnell Dockett suffered during Monday’s practice. The team said on Twitter that he tore his right ACL and needs season-ending surgery.

He suffered the injury about an hour into Monday’s practice on a passing play during an 11-on-11 period. Dockett was carted off the field at University of Phoenix Stadium after being attended to by head trainer Tom Reed.

Dockett has been a poster child for durability. He has missed just two games in his 10-year career.  Dockett, a three-time Pro Bowler who shares the Super Bowl sack record with Reggie White, is coming off his best season — 59 tackles and 4.5 sacks — in about five years.

This is obviously a huge blow to the Cardinals defense, which lost linebacker Karlos Dansby in free agency, and will be without suspended linebacker Daryl Washington.
