Sources say that Colts quarterback Peyton Manning is out for the duration of the 2011 season after he will likely require his second neck surgery in under a year.

As of this hour, the major sports media have not confirmed this report and Peyton’s father Archie declined to comment when asked about the story.

Both @incarceratedbob on twitter and John Michael Vincent of ESPN 1070 in Indianapolis are reporting that Manning will have another neck surgery, which would mean he will be out of the season.  Obviously this news has major fantasy football implications and greatly hurts the Colts chances this season.

Manning was removed from the Colts physically unable to perform list on August 29, but his progress was slower than expected.  The Colts signed veteran QB Kerry Collins out of retirement as Manning’s backup.  He will likely start for the Colts this season.
