Indianapolis Colts wide receiver Darrius Heyward-Bey is day-to-day with a left knee sprain.
Coach Chuck Pagano said Tuesday that an MRI revealed no significant ligament damage.
Heyward-Bey has not practiced since injuring knee during practice on Sunday. He wore a brace Monday and was walking gingerly without crutches.
Also, the team signed fullback Robert Hughes, who played five games with the Colts last season.
