Colts QB Peyton Manning is already ruled out for Week One, and rumors are swirling about when he will be able to return.

A radio host in Indianapolis reported Wednesday that Manning underwent another surgery on his neck and would miss the entire 2011 season. Colts owner Jim Irsay took to Twitter to respond to the report on Wednesday night, saying that Manning did not have a medical procedure last Sunday.

Sports Illustrated's Peter King reported that Manning could have another procedure, but it has not happened yet.

On Thursday morning, Irsay wrote on his Twitter that "#18's out for awhile."

By missing Sunday's opener, Manning ends a streak of 208 consecutive regular-season starts, the longest active streak in the NFL. Kerry Collins will start on Sunday vs. the Texans.

The way we see it

Manning isn't ruled out for the season, yet, but it seems that anything is possible with this injury. Irsay's latest tweet saying Manning will be out "for awhile" confirms that this is no ordinary injury and Manning cannot be rushed back to the field.
