The Indianapolis Colts continued their offseason trend of adding competition to the roster, signing free-agent running back Christine Michael, the team announced Thursday.

In a corresponding move, the Colts waived running back Brandon Radcliff.

Michael, 26, will join a Colts backfield that already features veterans Frank Gore, Robert Turbin, Josh Ferguson and rookie Marlon Mack. Gore and Turbin are projected to be the team's top two running backs next season.

New general manager Chris Ballard has put a premium on adding as much depth and competition to the roster as possible as the Colts try to end their two-year absence from the playoffs. He has also said he plans to add players and make adjustments to the roster throughout the year, which is why the Michael signing shouldn't be surprising.
