SAN FRANCISCO -- Cowboys quarterback Tony Romo fractured a rib in the first half of Sunday's game against San Francisco but returned for the final drive of the third quarter with his team trailing 21-14.
The Cowboys eventually rallied during the fourth quarter and won, 27-24, on a field goal during overtime.
A source told ESPN's Ed Werder the team believes Romo fractured two different ribs. Romo will undergo a CT scan Monday, the source said.
Romo came back moments after the team announced he had a broken rib and wouldn't return. He was clearly uncomfortable, grimacing at times.
"It's got to be one of those things that will follow him
through his career. I know what it was here in the locker room at
halftime. I know what he had to do to get back on the field,"
Cowboys owner Jerry Jones said.
"I know what he had to do before (painkillers) took hold to
relieve him from his pain. But, boy, did he come back. That was
Romo, who completed 20 of 33 passes for 345 yards in the win, didn't take a pain-killing injection or wearing any equipment to protect the injured area, sources told Werder.
"Ribs are tough," Romo said. "It's just hard to breathe, and
talk really. You have to talk loud, especially on the road."
Romo came out of the locker room after the second-half kickoff and walked onto the field briefly as Kitna returned to the sideline, then Romo came off and later returned slowly to the locker room. He kicked the ground in frustration.
Back on the sideline late in the third quarter, Romo tapped
Jason Garrett on the shoulder and told the coach to put him back in
"Eventually, what was convincing was, 'At some point I'm going
to play with this thing, so why not now?' " Garrett said, quoting
Romo. "It's about a quarterback but it's really about a football
player and a competitor. And Tony is that. One of the best
competitors I've ever been around."
Romo said: "I just told him I was good to go. I think he asked some of the
guys. I didn't give him too much of a chance. I just
ran on the field."
Romo played through multiple hits in the first half, when he threw a late 53-yard TD pass to Austin to bring Dallas within 14-7.
Romo came up slowly after being hit on a blindside cornerback blitz by Carlos Rogers as he was throwing in the second quarter.
Romo, who said this week he would come out and play his "best game" after blowing a 14-point lead last Sunday night against the Jets, went 8 for 17 for 144 yards and the TD before leaving the game.
