After dealing with a wave of injuries, most notably to star quarterback Andrew Luck, the Colts are on the verge of getting one of their key contributors back on the field.

Indianapolis left tackle Anthony Castonzo, who missed the last two games with a knee injury, said this week he's closing in on a return to the lineup.

Per the team's official website, Castonzo told FOX Sports 97.5 in Indianapolis that he hasn't ruled out playing in Sunday's game against the Jacksonville Jaguars, but added the Colts' Week 15 matchup against the Houston Texans is a more likely target.

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

Castonzo, who started 66 games before being injured, was hurt in the Colts' 24-21 win over the Atlanta Falcons on Nov. 21.

Joe Reitz has filled in at left tackle the last two games in Castonzo's absence.
