Cowboys tight end James Hanna set for knee surgery

FRISCO, Texas -- Dallas Cowboys tight end James Hanna will undergo season-ending knee surgery on Tuesday, according to sources.

Hanna was placed on the physically unable to perform list at the start of training camp with what was described as a bone bruise. He had surgery in the middle of August with the idea of him returning sometime in the regular season.

With needing to have his three-week practice window started Tuesday and not being close to playing, Hanna has opted for a second surgery in three months.

He will be the second tight end to undergo surgery in as many weeks. Geoff Swaim had surgery last week to repair a torn right pectoral tendon.

The Cowboys have only two tight ends -- Jason Witten and Gavin Escobar -- on the active roster. They called up wide receiver Vince Mayle from the practice squad last week and he served in a quasi-tight end role in Sunday’s win against the Baltimore Ravens.

The Cowboys re-signed Hanna to a three-year, $8.25 million deal in the offseason. A sixth-round pick in 2012, Hanna had developed into a solid second tight end behind Witten as a blocker. He has started 29 of 62 games to go along with 33 catches for 286 yards.
