Injury roundup: Colts' Ryan Kelly still week to week

Andrew Luckwon't be the only name missing when the Colts square off with the Rams on Sunday.

The team's starting center, Ryan Kelly, has also been ruled out for the regular-season opener after undergoing August foot surgery.

First-year general manager Chris Ballard announced Monday that Kelly remains week-to-week, but said optimistically, per the team's official site: "He's close."

In place of the second-year Kelly, rookie Deyshawn Bond will start for a Colts team set to "unleash" Scott Tolzien at quarterback ahead of the traded for Jacoby Brissett, with Ballard calling the ex-Patriots passer more of a "long-term" option for the club.

Kelly's short-term timeline is somewhat surprising on the heels of reports that the second-year pivot could miss six-to-eight weeks as a logical candidate for IR Recall.

Getting Kelly -- and Luck -- back sooner than later would steer this Colts ship back into friendly waters after a truly dark end to the summer.
