The Dallas Cowboys officially ended Tony Romo's season by putting the quarterback on injured reserve Tuesday. Romo has been out since suffering a fractured left collarbone in the second quarter of an Oct. 25 loss to the New York Giants. He was given a six-to-eight-week recovery time but discomfort remains, and he does not have full range of motion or strength. Owner and general manager Jerry Jones had hoped Romo would be able to return this season but acknowledged after Sunday's win against Washington that it was doubtful. Jon Kitna has a 4-4 record as Romo's backup and has thrown for 2,250 yards with 15 touchdown and 10 interceptions. He has a 91.4 passer rating. The Cowboys were 1-5 in Romo's six starts. He finishes the season with 1,605 passing yards, 11 touchdowns and seven interceptions. He had a 94.9 passer rating. Read more: http://sports.espn.go.com/dallas/nfl/news/story?id=5942560
