ANDERSON, Ind. -- The rehabilitation process for Jeff Saturday likely is in the two-to-six week range after the Indianapolis Colts' Pro Bowl center underwent arthroscopic surgery on one of his knees.
At least that's the expectation of owner Jim Irsay.
"With scopes you never know,'' he said following this morning's practice at Anderson University. "We've seen guys come back in two weeks, you see some guys come back in six weeks.
"You're hoping it's the shorter side of the scale. It just depends on the guy, how quick he can rebound.''
A six-week rehab would mean Saturday would not be ready for the Colts' Sept. 12 regular-season opener at Houston. The team said Saturday had "a loose body'' removed from one of his knees on Tuesday.
Saturday has started 154 regular-season games since 2000 when he became quarterback Peyton Manning's center. He's been selected to four Pro Bowls during that stretch.
Until Saturday returns, Jamey Richard and Mike Pollak likely will divvy up the playing time at center.
"It's definitely the next-guy-in theory and all that, but it's definitely going to be tough without him,'' Pro Bowl tight end Dallas Clark said. "But we've got a lot of young guys who are ready to step in and make plays," he said.
"They won't do it quite as good as Jeff, but that's the beauty of the game. It will give them chances to get some reps and good looks.''
Saturday's rehab is compounded by the continued absences of starting left tackle Charlie Johnson and rookie interior lineman Jacques McClendon. Johnson sprained his right foot last week while the team has not disclosed McClendon's injury.
