Yahoo’s Jason Cole hears from 2 separate sources that QB Peyton Manning’s career could be over. "The nerves in Manning’s arm are not healing as quickly as hoped and, worse, don’t appear to be progressing at enough of a rate to indicate that he will play again," Cole writes. "He hasn’t shown improvement in velocity on his passes, and the two sources fear he likely never will again… Manning has hit a plateau in his rehabilitation in terms of getting stronger, both sources said. While atrophy in the arm was expected, the fact that it hasn’t improved recently is an ominous sign." We reported way back in early October that the neurosurgeon who operated on Manning described the nerve in his throwing arm as "dead." Sounds like that was an accurate assessment. The talk over the past month has been about whether or not Manning will return to Indy. The more relevant question at this point is whether or not he’ll return to the football field at all.
