Colts' Clint Session has broken arm

INDIANAPOLIS -- A broken arm and a dislocated elbow couldn't prevent Colts linebacker Clint Session from finishing Monday night's game against Houston.

The injuries might, however, end his season.

Session's agent, Harold Lewis, could only confirm the injuries to Session's right arm. He later said that Session hoped to be playing Sunday at Philadelphia.

Colts coach Jim Caldwell has provided no update on Session's status this week.

"I have not heard that," Lewis said Thursday when asked about Session going on injured reserve. "He played half a game with a dislocated elbow and a broken forearm, so it would take a lot more for him not to play."

NFL.com first reported the extent of Session's injuries.

The latest news is another blow to the Colts' attempt to defend their AFC title.

They already have 11 players on season-ending injured reserve, including All-Pro tight end Dallas Clark (wrist), safety Melvin Bullitt (safety), kick returner Devin Moore (nerve damage) and rookie cornerback Kevin Thomas (knee), a third-round pick who was injured during minicamp.

That's only a partial list.

Safety Bob Sanders, the 2007 NFL defensive player of the year, hasn't played since the first quarter of the season opener because of a torn biceps muscle. Receiver Austin Collie missed Monday night's game after having surgery on his right thumb during the bye week. Collie was a full participant in Thursday's practice, an indication that he might play Sunday at Philadelphia.

The news wasn't as good for the Colts' backfield. Running back Joseph Addai hasn't practiced since injuring a nerve in his left shoulder Oct. 17 at Washington and his replacement, Mike Hart, has missed both days of practice this week with a sore ankle after running for a career-high 84 yards against the Texans.

Now, Session joins the list for the second time this year. He missed two games in September with a hamstring injury.

"All I know is that one of my associates was at the game, and he said the guy was a friggin' animal," Lewis said. "Somehow he got through it."

Session finished the game with eight tackles and his first sack of the season. He is fourth on the team in tackles with 38 and is one of the Colts' most energetic players.

He went down with 6:14 left in the first half after tackling Andre Johnson 1-yard short of a first down on third-and-10. Session stayed out for the rest of the first half, when Houston ran only three more plays, but he was back in the lineup at the start of the second half and played the rest of the night.
