Jon Kitna's career in doubt

IRVING, Texas -- Cowboys owner/general manger Jerry Jones said he's not sure if backup quarterback Jon Kitna will return in 2012, not so much to Dallas but any NFL team.

Kitna, in the last year of his contract, was placed on injured reserve Dec. 14 with an injured back.

The 15-year veteran played in two games this season and was inactive for four games with a back issue. He tried to throw prior to the New York Giants game Dec. 11 but felt discomfort.

"As a matter of fact, actually it bothered him a little bit and that impacted our decision a little bit," Jones said of Kitna

A few days before placing Kitna on IR, the team also moved running back Phillip Tanner to injured reserve with a hamstring injury. There was a thought the Cowboys put Tanner on IR too soon. But Jones indicated Tanner, even if on the active roster, wouldn't be ready to play even now.

"It's a good example of what can happen to you when you think you're deep at a position and then all of a sudden the injury bug can bite," Jones said. "And there is no orderly way the injury bug comes around. On the other hand, we know today Tanner wouldn't be ready and really questionable if he would have been ready and certainly in the early parts of the playoffs."

The Cowboys moved Stephen McGee up to No. 2 on the depth chart behind Tony Romo when Kitna was lost for the season. Quarterback Chris Greisen was signed to the practice squad on Dec. 14.
