INDIANAPOLIS – On Tuesday, Anthony Castonzo updated his status coming back from a sprained MCL.

Castonzo wouldn't totally rule out Sunday's game in Jacksonville for his return, with the more likely date being 12/20, when Houston visits Indianapolis.

"I would say that there's still a possibility of this week," Castonzo told WNDE on Tuesday. "I think 100 percent I'll be back next week (against the Texans)."

The return of Castonzo would allow for the Colts to go back to their normal starting offensive line with him at left tackle, Jack Mewhort at left guard, Jonotthan Harrison at center, Hugh Thornton at right guard and Joe Reitz at right tackle.

Not having Castonzo in the lineup has been something the Colts haven't had to deal with since his rookie season of 2011.

Before this injury, the last time Castonzo wasn't in the starting lineup was 66 games ago.

Castonzo's injury came in the team's win over Atlanta two weeks ago.

On the play prior to the two-minute warning, the Colts starting left tackle was rolled up on and could feel something in his right knee.

When the athletic trainers came out at the two-minute warning timeout, Castonzo told them he thought something was wrong his knee. The big man was able to put weight on it though ("bouncing around") and he eventually told the trainers he was fine.

Once Castonzo turned out of the huddle for the next play though, he knew something was definitely not right.

"I started yelling to the sidelines," Castonzo said re-telling the story.

Castonzo held up for one play before coming to the sidelines for the final three plays of that 24-21 victory.

In Castonzo's absence, Reitz has filled in at left tackle. Reitz will likely make his third start over there Sunday in Jacksonville with Chuck Pagano still listing Castonzo as "week-to-week."

It's looking like the Colts will get their franchise left tackle back though in the very near future.
