The neck injury to Athletics outfielder Coco Crisp could be potentially very serious. CBSSports.com Baseball Insider Jon Heyman reports Crisp may require season-ending neck surgery, though Crisp is getting other opinions before making a decision.

Crisp had an MRI on Thursday and hasn't played since suffering the injury on Tuesday. The team has not provided any further updates on his status, but he is unlikely to play this weekend in Tampa.
