Tony Romo knew he was risking another left collarbone injury by coming back eight weeks after breaking it. Cowboys owner and general manager Jerry Jones said on his radio show Friday that Romo would sit out the remaining five games with a small fracture in the same collarbone that had already sidelined him for seven games. ''The hard part is playing when you're trying not to get hurt, which is silly,'' Romo said after he threw three interceptions and Carolina returned two of them for touchdowns before the injury.
