The Colts issued the following statement regarding Manning's surgery:
UPDATE: "As previously stated on Monday, Sept. 5th, Peyton Manning has undergone further testing and consultation with several specialists regarding his rehabilitation. The results of these tests and the consensus of the consultations was that further surgery was warranted. Peyton has undergone this surgery today by having a single level anterior fusion. The surgery was un-eventful.
"This procedure is performed regularly throughout the country on persons from all walks of life, including professional football players. Two former Colts players had this same procedure last winter and have fully resumed their careers. Rehabilitation from such surgery is typically an involved process. Therefore, there will be no estimation of a return date at this time. We will keep Peyton on the active roster until we have a clearer picture of his recovery process.
"Peyton will immediately begin the rehabilitation regimen mapped out by the surgeon. We anticipate no further updates or availabilities beyond those required by the NFL Media Policy for the immediate future. Thank you for your consideration."
ESPN reported Manning had cervical fusion surgery and is out at least two to three months. Under that timetable, it's possible he could play again this season.
"Peyton didn't have a medical procedure last sunday, we'll have more info 2 add clarity 2 situation soon," Colts owner Jim Irsay wrote on his Twitter account. "#18's (Manning's number) out for awhile,but compete,we will/BELIEVE."
Manning was already ruled out for this week's season opener.
"I think he's OK, probably because there's a little finality to this deal in terms of playing," Archie Manning, Manning's father, told ESPN. "He's been on the clock since May. He didn't make it. Obviously, it's a big letdown, but he can relax a little bit compared to the intensity of everything he has done trying to rehab."
The Colts signed quarterback Kerry Collins during the preseason to operate as Manning's replacement. He's being paid $4 million this season.
