Tony Romo has broken rib, too

— -- CHICAGO -- Tony Romo has been dealing with the effects of back surgery this past offseason and two transverse process fractures, and the Dallas Cowboys quarterback let it slip Thursday night that he also has been playing with a broken rib for the better part of two months.

Romo said he was not sure in which game he suffered the injury, either Sept. 21 against the St. Louis Rams or Oct. 5 against the New Orleans Saints.

In 2011, he played through a broken rib and punctured lung, and in the 2008 season finale against the Philadelphia Eagles, he played with a cartilage tear in his ribs.

"It'll be nice when it's just about the back [surgery] instead of all the other junk," Romo said.

A source on Friday downplayed the seriousness of the injury, saying Romo had an injury to the cartilage and that the rib was not broken. Also Friday, NFL spokesman Brian McCarthy confirmed that  the league is looking into Romo's injury situation in regard to the injury report.

Romo said the transverse process fractures in his back are all but healed and the ribs have felt better. He wears extra protection for his ribs and has a longer-than-normal back plate to protect his surgically repaired back. He suffered the transverse process fractures when he took a knee to the back Oct. 27 against the Washington Redskins.

After struggling in the Thanksgiving Day loss to the Eagles with just four days of rest, Romo rebounded in Thursday's 41-28 win against the Chicago Bears, completing 21 of 26 passes for 205 yards and three touchdowns. He was sacked just once.

"I took a [pain-killing] shot this week," Romo said. "I didn't last week in the Eagles game, and that was a poor decision I think."

Romo will have 10 days off before the Cowboys play the Eagles Dec. 14 at Lincoln Financial Field.

"I'll probably start on Philly a little tonight on the plane," Romo said. "Then from there I think I'll probably do a little bit of work [Friday] during the day. I'll go ahead and get some treatment and ... take off Friday night and Saturday and probably come back on my own on Sunday."
