"Peyton Manning's agent, Tom Condon, said in an appearance on NFL Network Friday morning that he believes Manning will be healthy and ready to go for the 2012 season.

"Peyton's not done," Condon said.

Following up on Thursday's reports that Manning had been medically cleared to return to the field — reports that Colts owner Jim Irsay denied — Condon said that Manning's medical clearance means it would be safe for him to play, and that he wouldn't be risking greater injury to his neck. Condon added, however, that Manning's nerve regeneration hasn't reached the point where he would be able to step on the field and play in an NFL game today.

But Condon was adamant that anyone who thinks Manning would be foolishly risking his future health if he returns to the field is wrong. Condon said doctors including "the best back and neck guy in the country" have examined Manning and "made a determination that he's structurally sound.""
