Browns linebacker Eric Barton is weighing his options on whether or not to have season-ending surgery on the bulging disc in his neck, league source said. Barton, who was told by a Cleveland Clinic specialist that he has a bulging disc between the C3 and C4 vertebrae, is seeking a second opinion from an independent doctor, the source said. The Browns are giving him ample time to make his decision, but his season might be over whether or not he has the surgery. "Eric is going through tests and we’ll see where it is,'' said Browns coach Eric Mangini. "That’s where we’re at right now, just testing and evaluating, then we’ll make a decision.”
