Indianapolis Colts quarterback Peyton Manning had further neck surgery Thursday, sources familiar with the situation said.

Manning decided to have the surgery, the sources said, after consultation with a half-dozen doctors who reached a consensus that the most viable option would be a one-level cervical neck fusion in the wake of his May 23 surgery to repair a bulging disk. It’s unclear whether Manning would be able to return to play this season.

Colts owner Jim Irsay suggested via his Twitter account, an announcement is forthcoming. On Wednesday night, Irsay tweeted: “Peyton didn’t have a medical procedure last sunday, we’ll have more info 2 add clarity 2 situation soon.” On Thursday, Irsay tweeted: “NFL Season opens 2nite! We had a good practice yesterday and r guys r fired up 4 the season.#18’s (Manning’s number) out for awhile,but compete,we will/BELIEVE.” And Colts coach Jim Caldwell said Thursday at a news conference he anticipated more clarity on Manning’s prognosis soon.

Manning was unavailable for comment, as was his agent, Tom Condon. His father, Archie, and brother, Cooper, whose college career was ended by a severe neck injury, would not specifically address Peyton’s surgical decision.

Archie Manning, a former NFL quarterback, only spoke of his son’s state of mind.

“I think he’s OK, probably because there’s a little finality to this deal in terms of playing,” the elder Manning told Mortensen. “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.”

Without confirming any pending surgery for brother Peyton, Cooper Manning told ESPN that a cervical fusion would be a logical step after his brother’s slow recovery and setback last week when he experienced more upper back and neck pain.

“Everyone is different, but I’ve had a fusion and I’ve known players who have had fusions and went on to play football. … You can get a pretty good range of motion back and much more stability once it heals,” said Cooper, the oldest of three brothers that include quarterbacks Peyton and Eli.

Cooper said he did not have specific knowledge on a decision regarding another operation for Peyton.

“You know Peyton and how he values his privacy even within a very tight family like we have,” he said. “We’ve exchanged some short texts and I’ve given him his space. He’s had a lot going on.”
