The Arizona Cardinals confirmed starting defensive tackle Darnell Dockett will be lost for the season after tearing a knee ligament during training camp Monday.
Docket was taken off the field on a cart after injuring his right knee and an MRI confirmed he suffered a torn anterior cruciate ligament.
Dockett hurt his knee during an 11-on-11 drill and appeared to have gotten his foot stuck in the Cardinals' practice field turf.
He limped off, then was placed on a cart and taken away. Frostee Rucker moved into Dockett's spot.
Arizona also has undrafted Bruce Gaston, draftee Kareem martin and Ed Stinston on the line who can play the position.
Dockett is in his 11th NFL season, all with the Cardinals. He and Larry Fitzgerald have the longest tenure of any Arizona players.
He missed on two games his entire career with the Cardinals.
Dockett is a three-time Pro Bowl player. Since 2004, his 158 starts are more than any other player in the NFL at his position
