THE NFL is looking into whether the Cowboys hid the fact that quarterback Tony Romo has had a broken rib for most of the previous 2 months, according to media repors.
"We're looking into it," NFL spokesman Greg Aiello said via email to NBC's ProFootballTalk.
Romo mentioned the injury after Thursday night's 41-28 win at Chicago.
"I took a [painkilling] shot this week," Romo said. "I didn't last week in the Eagles game, and that was a poor decision, I think."
ESPN reported that sources said Romo misspoke and that he had torn rib cartilage, not a break.
Since the injury was undisclosed, it had not appeared on the Cowboys' injury reports. A team is subject to a fine if the league finds it did not comply with its injury report rules.
Romo also has been playing with two transverse process fractures after he was kneed in the back during a Week 8 game against the Redskins. He missed the following week, a 28-17 home loss to the Cardinals. He said his back is almost healed and his ribs have been feeling better lately.
Via ESPNDallas.com, Romo said he's not sure when he suffered the injury, either Sept. 21 against the Rams or Oct. 5 against the Saints.
In the past, Romo also has played with a broken rib and a punctured lung.
* Jets coach Rex Ryan emphatically denied an SB Nation report, quoting anonymous players and management sources, that he twice wanted to fire offensive coordinator Marty Mornhinweg during the Jets' 2-10 season and that there is discord among the coaches and players.
"One hundred percent, I would deny that I'm looking to fire Marty or anybody," Ryan said.
The Jets' offense ranks 29th in overall yardage and last in passing in Mornhinweg's second season with the Jets.
"Rex and I are close," said Mornhinweg, a former Eagles offensive coordinator.
