Heyward-Bey returned to the practice field Tuesday night, the team announced. The Colts said he participated in individual drills.
Heyward-Bey injured his knee during practice Sunday. He wore a brace on his knee while watching practice Monday.
Depth at receiver will become a concern for the Colts if Heyward-Bey, who signed with them in the offseason after spending his first four years with the Oakland Raiders, is out for an extended period of time.
