Eric Foster dislocates right ankle

TAMPA, Fla. -- Indianapolis defensive tackle Eric Foster will spend the night in an area hospital after suffering a dislocated right ankle in the second quarter of the Colts' 24-17 loss to the Tampa Bay Buccaneers on Monday night.

Colts coach Jim Caldwell said Foster will have surgery on the ankle.

The injury occurred with 52 seconds remaining in the half and the Colts leading 10-7. Foster got tangled up with the pile while trying to assist on a tackle and remained down after the play. He was immediately attended to by the training staff, fitted with an air cast and left the field on a cart.

Foster pounded his chest and yelled to teammates as he left the field to applause.

Foster, out of Rutgers, is in his fourth season. He entered the game with 12 tackles.

The Colts also lost starting offensive linemen Anthony Castonzo and Ben Ijalana to injuries during the game. Guard Ryan Diem was inactive.

"I think you have to deal with injuries in this business," Colts coach Jim Caldwell said. "They happen. You just have to find a way to overcome it. That's what we talk about -- the next man up. Somebody has got to fill in and be ready to play."
