Colts TE Dwayne Allen out for season
Indianapolis coach Chuck Pagano made the announcement on Wednesday. The Colts had hoped Allen would heal with rest, but doctors say surgery is required.
The Colts already have lost starting running back Vick Ballard and starting left guard Donald Thomas to season-ending injuries. Ballard tore the anterior cruciate ligament in his right knee last week. Thomas has torn a quad tendon in his right leg.
Pagano says Thomas will have surgery on Thursday.
