Reitz suffered a high-ankle sprain in Thursday's preseason game, the Indianapolis Star reports.

Indianapolis already has some weaknesses on the interior offensive line, so losing a key backup for a few weeks won't help.

Colts re-signed OG Joe Reitz to a one-year, $1.431 million contract.

Reitz was a restricted free agent. Reitz appeared in 14 games last season, and has made 20 starts over the past three years. Reitz can start in a pinch, but is ticketed for a reserve role.

Reserve Colts OG Joe Reitz has been diagnosed with a concussion.

Reitz started in Week 14, but was limited to 13 snaps against the Texans. He should be considered day to day.

Colts re-signed exclusive rights free agent OG Joe Reitz.

Reitz started eight games at left guard last season, but was an adventure both as a run blocker and pass protector. Reitz will face competition in the form of FA signee Donald Thomas or a draft pick. Ideally for Indy, he'd lose. Jeff Linkenbach is another (bad) option. Thomas may supplant Mike McGlynn at right guard.

Colts LG Joe Reitz (concussion) has been ruled out for the Wild Card Round.

Reitz graded out negatively as both a run and pass blocker this regular season by Pro Football Focus. Of course, backup Jeff Linkenbach was even worse. It's a concerning loss because Haloti Ngata often lines up over the opposing left guard. As it was all year, line play will be a weakness for Indy in the playoffs.

Colts LG Joe Reitz did not return after sustaining a head injury in Week 17.

He may have to go through the NFL's testing protocol. Reitz also left the Week 13 game with a head injury, appearing dazed while being carted off the field. Backup Jeff Linkenbach would be a liability if forced to start at Baltimore on Sunday.

Colts LG Joe Reitz left Sunday's Week 13 game against the Lions with an undisclosed injury.

Reitz went down early in the first quarter and appeared dazed as he was carted off the field. Consider him doubtful to return. Jeff Linkenbach has come on at left guard.

Coach Chuck Pagano confirmed LG Joe Reitz had a "minor" surgical procedure on his knee.

That explains Reitz's extended absence. Pagano expects both Reitz and ILB Pat Angerer (foot) to return against the Packers after the Week 4 bye. Seth Olsen, a major liability in pass protection, has been filling in for Reitz.

Colts LG Joe Reitz (knee) missed practice all week and is out for Week 1.

Reitz didn't even travel with the team. Seth Olsen will step in and man the position in Reitz's absence, while Jeff Linkenbach backs up. Andrew Luck's protection is going to be shaky all season long.

Colts LG Joe Reitz was forced from Thursday's game in the third quarter with an ankle injury.

Backup center Mike Pollack has come on to replace Reitz, who is questionable to return.

Colts LG Joe Reitz underwent arthroscopic surgery on his knee on Tuesday.

Reitz isn't in danger of being placed on injured reserve, so there's a good chance he'll return within a few weeks. Veteran Jamey Richard was re-signed to add depth on the interior.

Colts promoted OT Joe Reitz from their practice squad.

A big project at 6'7/320, Reitz went undrafted out of Western Michigan in 2008 and has bounced around since. He'll likely be inactive for the playoffs.

Colts waived OT Joe Reitz.

Reitz is getting a journeyman tag already. He's been cut three times this month.

Colts claimed OT Joe Reitz off waivers from the Dolphins.

Reitz has changed homes three times in the past four days on waiver claims. The developmental prospect fits Indianapolis' scheme as a heady athlete, but both the Ravens and Fins deemed him not ready to play in games.

Dolphins waived OT Joe Reitz.

Reitz is the guy that goes to make room for KR Clifton Smith. Once Reitz clears waivers, he's expected to head to the practice squad.

Dolphins claimed OT Joe Reitz off waivers from the Ravens and DE Robert Rose off waivers from the Seahawks.

More developmental projects, the Fins are loading up on high-upside big bodies at the end of their roster. Reitz is 6'7, about 280. Rose is 6'5/285.
