Colts re-signed CB Darius Butler to a two-year contract.
The 26-year-old onetime second-round bust resurrected his career in Indianapolis last season, recording four interceptions as the slot corner between Vontae Davis and Jerraud Powers. The Colts now have a formidable top-three cornerback trio with Greg Toler and Davis on the outside, and Butler covering slot receivers. Indy could still afford to add a safety, upgrading on Tom Zbikowski.
