Jim Irsay isn't worried about Peyton Manning's health yet, according to an ESPN.com report. He's just not entirely sure when Manning will start throwing to his teammates. The Colts' owner told reporters Thursday in Atlanta he doesn't expect offseason neck surgery to prevent Indianapolis' franchise player from playing at his usually high level. "My sense is that he's doing well," Irsay said at the league's owner meetings. "We've been through (his neck) surgery before. So I anticipate him being ready."
