Dak Prescott leaves game early with hand injury after banging it twice on throws

When a quarterback follows through on a throw, he's in danger of hitting a helmet or a defensive lineman's hand. It's a hazard of the job. 

It's unlucky to do it twice in a row, and painful. Dallas Cowboys quarterback Dak Prescott had to leave Sunday night's game after hitting his right throwing hand on defensive linemen twice in the same fourth quarter drive. 

In the middle of the drive, Cooper Rush came on the field while Prescott went to the sideline. Prescott was looked at by trainers and then jogged to the locker room, presumably to get an X-ray. That led to some nervous moments for the Cowboys. 

It was an ugly night for the Cowboys offense. Prescott couldn't get much going against the Tampa Bay Buccaneers. But losing a game just lingers for a week. A hand injury to Prescott would be a much harsher blow.
