An Indianapolis area radio host reported on Wednesday that Indianapolis Colts superstar quarterback Peyton Manning had another neck surgery on Sunday and is out for the season, though Colts owner Jim Irsay later disputed parts of the account on Twitter.

Jake Query, a radio show host for 1260 WNDE, reported on Twitter that two reputable sources told him that Manning underwent a third neck procedure on either Sunday or Monday and is subsequently out for the year.

A source I consider reliable told me he is out for the season, Query tweeted.

But at 10 p.m. EST, Irsay tweeted, Peyton didn't have a medical procedure last Sunday, we'll have more info 2 add clarity 2 situation soon.

On Thursday morning, the Colts owner tweeted, #18's out for awhile,but compete,we will/BELIEVE.

Although the owner doesn't go all the way to confirm Manning is out for the season, the tweet certainly shows just how dire the situation is.

The news comes a day after the Colts said Manning would miss at least the team's home opener against the Houston Texans on Sept. 11. Recently signed backup Kerry Collins is expected to start on Sunday.

Manning, who hasn't missed a start in 227 consecutive games, was understandably upset about missing the team's highly anticipated opener.

 To say I am disappointed in not being able to play is an understatement, Manning said in a statement. The best part about football is being out there on the field with my teammates.

It will be tough not to be out there playing for the organization and our fans. I simply am not healthy enough to play, and I am doing everything I can to get my health back.

The team entered the preseason with high expectations to win the AFC South division, but could struggle if Manning is indeed out for the year. While Manning believes the team will do fine without me, it is doubtful Collins -- a fine veteran in his own right -- can have quite the impact Manning has had on the offense during his illustrious 14-year career.
