Arizona Cardinals wide receiver Christian Kirk has been ruled out for Sunday's game against the Cincinnati Bengals at Paul Brown Stadium.
According to Bob McManaman of the Arizona Republic, Cardinals head coach Kliff Kingsbury said Kirk's ankle injury is a sprain that will not require surgery. Kingsbury also noted that it's possible Kirk will be able to play in Week 6 against the Atlanta Falcons.
Kirk has built on a solid rookie campaign that saw him record 43 catches for 590 yards and three touchdowns as Arizona's primary deep threat.
