Colts veteran LT Castonzo retires

INDIANAPOLIS— Anthony Castonzo, the Indianapolis Colts’ longtime left tackle, announced his retirement Tuesday.

The 32-year-old had been an anchor on Indy’s offensive line since he was the No. 22 overall draft pick in 2011.

His decision came three days after the Colts were eliminated from the playoffs at Buffalo and less than two weeks after he had season-ending ankle surgery.

Castonzo considered retiring last year, but eventually agreed to a two-year contract extension with the Colts.

But this season, he missed four regular-season games and the playoff game with rib, knee and ankle injuries.
