Cowboys owner Jerry Jones hopes that quarterback Tony Romo will play again this season. Jones said that Romo threw Sunday for the first time since breaking his left collarbone in the Oct. 25 loss to the Giants. The injury is expected to sideline Romo for at least another three weeks, according to a source. Romo was due for X-rays either Sunday or Monday, according to sources, but Jones said after the game that X-rays weren't necessary at this point. "X-rays won't help us, relative to how and what degree it's mended and what degree it can take a lick," Jones said. "There may be some just to see if there's some kind of technical alignment or something like that, and I'm not real qualified or knowledgeable to talk about that. But we didn't think an X-ray or X-rays or those type of things will help us make a decision. It's going to be how it's feeling."
