Yet another offensive line combo for Colts

Through seven games the Colts have used four different starting offensive line combinations.

Sunday in Tennessee, we’ll see number five.

The team announced Joe Reitz, who has started every game at left guard, is out for an unspecified amount of time after arthroscopic knee surgery.

Indianapolis has signed two familiar players to restock the line: guard Jamey Richard and tackle Michael Toudouze. The team has also placed quarterback Kerry Collins and fullback Chris Gronkowski on IR.

That means the Colts’ offense belongs to Curtis Painter as long as he can stay healthy, with Dan Orlovsky as the backup. Of course there remains the possibility that Peyton Manning re-emerges late in the season.

Reitz is likely to be replaced by Seth Olsen, who filled in after Reitz was hurt during the blowout in New Orleans on Sunday night.

The health of two other starters is also in question. Left tackle Anthony Castonzo has missed the last three games and right guard/tackle Ryan Diem has missed four of the last five.

Both are dealing with ankle injuries.

It's likely the end for Collins, who had retired from the NFL before the Colts lured him back just before the season, concerned about Painter's readiness with Manning out.

Collins suffered a concussion Sept. 25 against Pittsburgh and hadn't played since.
