Turns out the Colts were indeed attempting to lure a veteran quarterback out of retirement, as Irsay tweeted earlier this week. It just didn’t happen to be Brett Favre.

Manning, who has the longest active consecutive-starts streak at 227 (regular-season and playoff games), is recovering from surgery in May to repair a disk problem. His recovery and rehab were hampered when he could not work with Colts trainers during the lockout.

Although Manning’s former coach, Tony Dungy, said he’d have to be dead not to start in the season opener, the date is drawing closer and, clearly, Curtis Painter and Dan Orlovsky are not viable options. And, just as clearly, Manning’s status is in serious doubt. In fact, ESPN’s Chris Mortensen is reporting that, while Manning is hopeful, the Colts’ leaders do not believe he will be ready when the team plays Houston in the regular-season opener Sept. 11.

Collins, 38, had announced his retirement July 7 after five seasons with the Tennessee Titans but has deep ties to the Colts. The team’s president, Bill Polian, was general manager of the Carolina Panthers when he took Collins in the first round of the 1995 draft and Colts Coach Jim Caldwell coached Collins at Penn State.

Collins, who has also played for the New Orleans Saints, New York Giants, and Oakland Raiders, is second among active quarterbacks in passing yards, completions and attempts. He trails only ... Peyton Manning.

Speaking of whom, not that Tom Brady has any insights into the Colts’ thinking, but the New England Patriots’quarterback believes Manning will be under center when the regular season starts.

“He’ll be playing,” Brady said this morning. “You kidding me? He’ll be playing.”
