Felix Jones, Miles Austin hurt

The Dallas Cowboys outlasted San Francisco 27-24 in overtime Sunday, but their offense may have suffered some major losses.

Cowboys owner Jerry Jones said running back Felix Jones separated his right shoulder on the fifth snap of the game. And wide receiver Miles Austin aggravated his hamstring, an injury he suffered in the preseason. Both players will be re-evaluated Monday.

Jones and Austin weren't the only ones playing hurt, either. Quarterback Tony Romo fractured a rib in the first half but returned for the final drive of the third quarter. A source told ESPN's Ed Werder that the team believes Romo fractured two different ribs. Romo will undergo a CT scan Monday, the source said.

Jones was fitted for a harness on the sideline and was able to return for the second series. As the game wore on, however, he was limited and rookie DeMarco Murray and Tashard Choice handled the tailback duties.

Jones, who finished with 25 yards on nine carries and caught one pass for five yards, will undergo an MRI on Monday.

Meanwhile, team sources told ESPN's Chris Mortensen that Austin, who tweaked the hamstring on a fourth-quarter run, could be out through the Cowboys' bye week (Oct. 9). Austin made three touchdown receptions among his nine catches for 143 yards, leaping over a defender and diving into the end zone to pull Dallas within 24-21 with 6:55 to play.

Elsewhere, tight end Jason Witten bruised his ribs on the second series after taking a hit from cornerback Carlos Rogers.

"I feel all right," said Witten, who finished with seven catches for 102 yards. "I just got a little bruised up there, but I'll be ready to go."

In the fourth quarter, center Phil Costa re-injured his posterior cruciate ligament in his right knee.

Cornerback Mike Jenkins had an ice bag on his left shoulder, but he managed to finish the game after getting knocked out twice in the season opener with a stinger and shoulder.

"I made it through all right, man," Jenkins said. "I'm maintaining. It's going to take a couple of weeks to get right, but hopefully I'll become at least 80 percent before next week."

The Cowboys host Washington on Sept. 26 on ESPN's Monday Night Football.

"That was an intense game with a lot of runs back and forth," Witten said. "We couldn't get the running game going. We'll need that extra day to get guys back. Miles played great. He should be back. It'll be good for Tony to get him healthy. It'll be good for everybody across the board."
