Rookie left guard Hugh Thornton did not practice Wednesday because of a neck injury. Joe Reitz was working at left guard during the portion of practice that was open to the media.
Fellow guard Jeff Linkenbach, who started against Tennessee last weekend, is already out with a quad injury. The Colts are calling Linkenbach week-to-week with his injury.
Coach Chuck Pagano said Wednesday that he's not sure who will start in Linkenbach's place against the Bengals. Linkenbach replaced Mike McGlynn at guard against the Titans. The Colts added Xavier Nixon to the 53-man roster from the practice squad on Tuesday.
"What we'll do with the offensive line, we'll just go through the week and between Mike and Joe and Hugh, we'll just work those guys through this week," Pagano said. Have not made any final decisions on anything as far as the offensive line goes. Just go to work on correcting things we need to correct. Nixon is a swing guy. He's played both. Major outside being a swing tackle type guy. That's where we're at with the offensive line."
The offensive line has had its problems all season, but this is a bad time for the Colts to be dealing with injuries there. They need to beat the Bengals to go up one game in the race for the No. 3 seed in the AFC playoffs. The Bengals are ninth in the league in sacks with 36.
"They're ranked sixth in the National Football League for good reason," Pagano said. "They got good players. Got a good front seven, good linebacking core, good in the back end."
Here's the rest of the Colts' injury report from Wednesday:
Cornerback Greg Toler and receiver T.Y. Hilton (shoulder) were limited in practice. Having Toler practice -- even if it was limited -- is a positive because he's missed the past five games with a groin injury.
