— -- GLENDALE, Ariz. -- The Arizona Cardinals' concerns about the seriousness of the right knee injury defensive tackle Darnell Dockett suffered during Monday's practice was confirmed, the team said Monday.

Arizona tweeted Dockett tore the ACL in his right knee and will need 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 was helped to the cart by Reed and center Lyle Sendlein, who has been out with a calf injury.

"It's always a scary moment bringing the cart out," Cardinals defensive end Calais Campbell said.

Dockett's defensive line teammates didn't see exactly what caused the injury, but nose tackle Dan Williams guessed Dockett got his foot stuck in the ground. Campbell said he didn't see or hear what happened to Dockett. 

While Dockett was lying on the ground, Campbell, quarterback Carson Palmer and wide receiver Larry Fitzgerald surrounded him.

"We count on him week in and week out to be a leader and take us where we want to go," Campbell said. "... Hopefully he'll come back soon."

Dockett has been a poster child for durability. He's missed just two games in his 10-year career -- both for injuries. He played in his first 104 games before a shoulder injury sidelined him in Week 9 of the 2010 season. He missed Week 4 in 2012 because of a hamstring injury.

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.
