Still, the Cardinals (9-5) won their sixth in seven games. With San Francisco and Carolina winning, they remain a game back of both for a NFC wild-card berth.
Tennessee (5-9) lost its third straight and eighth in 10 games. The Titans also lost their fifth consecutive home game for the first time since moving to Tennessee in 1997.
The Cardinals scored 21 straight points in the second half, the last when Cason returned his first interception for a TD and a 34-17 lead.
