Reggie Bush is active for the Miami Dolphins' game Sunday against the Arizona Cardinals, the team announced.
Cardinals defensive tackle Darnell Dockett won't play because of an injured hamstring.
Bush injured his knee last week versus the New York Jets and was listed as questionable.
The running back missed practice on Wednesday and was limited in practice on Thursday and Friday.
Bush leads the Dolphins in rushing with 302 yards on 50 attempts and two touchdowns through three games.
