The Indianapolis Colts signed running back Davin Meggett to the training camp roster Sunday.

Meggett was added after running back Vick Ballard was placed on injured reserve with a torn left Achilles' tendon. Meggett spent time with the Colts last season and has a good working knowledge of the offense.

The Colts also placed outside linebacker Aaron Morgan on injured reserve. There was no announcement on the type or severity of injury that Morgan sustained. He was in his first year with the Colts after spending time with the Tampa Bay Buccaneers and Jacksonville Jaguars.
