Peyton Manning and Jim Irsay agree on one thing: The Manning Era isn’t over in Indianapolis. Manning said yesterday he hopes to return to practice this year and still holds out hope of playing if doctors say he is finally healed from his Sept. 8 neck surgery. Irsay, the Colts’ owner, said he expects the four-time MVP still has some good years left. There are some big questions looming. The Colts must decide whether to opt out of Manning’s five-year contract or pay a $28 million bonus to keep him on the roster. And if they have a high draft pick next year, the Colts will have to decide whether to take Manning’s heir apparent, someone like Andrew Luck or Landry Jones. Manning hasn’t played since having surgery to repair a damaged nerve that caused weakness in his throwing arm. It was his third neck procedure in 19 months. “I think it’s too early to bury this era,’’ Irsay said. A few hours earlier, Manning made his second impromptu locker room appearance of the season, telling reporters that he’s spending every day in rehab and that he hopes to practice with his teammates in December and play in a game this season. But he hasn’t been cleared for football activity by the doctors. Irsay said there was less than a 50 percent chance Manning would appear in a game this season. Without their franchise quarterback, the Colts are 0-8 for the first time since 1997. “I miss playing, I really do. If I get cleared to play and I’m good enough, would I play? Absolutely,’’ he said. “I’d love to because that’s how I’m wired, that’s my job and I love my job.’’
