Dallas Cowboys owner and general manager Jerry Jones doesn't know whether quarterback Tony Romo will be able to play in Monday night's game against the Washington Redskins, saying the decision would primarily be based on Romo's pain management. Romo suffered a cracked rib and small puncture of his lung on the Cowboys' first series in Sunday's overtime win over the San Francisco 49ers. Romo sat out all but 37 seconds of the third quarter, as the medical staff wanted him to wait for pain-killing medicine to take effect. He completed 12 of 16 passes for 201 yards and a touchdown after his return, leading a rally from a 10-point deficit. The punctured lung was discovered in a CT scan Monday, which revealed evidence of pneumothorax, a collection of air or gas around the lungs. "I don't know. I really don't," Jones said when asked Tuesday on KRLD-FM whether Romo would play against the Redskins. "I understand the nature of the injury as much as you can without being in medicine. We'll just have to see how it goes. It has everything to do with just his ability to handle the pain, and we know he has a bunch of it. "We'll see how that goes. He'll be monitored obviously extremely closely regarding the pneumothorax and we'll see how it goes." Read more: http://espn.go.com/dallas/nfl/story...in-key-deciding-status-vs-washington-redskins
