DAVIE, Fla. (AP) -- Cornerback Chris Culliver has signed with the Miami Dolphins, who hope he can return from knee surgery and help their thin secondary.
Culliver tore ACL and MCL ligaments in his right knee during practice last Thanksgiving with the Washington Redskins, and they released him in May. He had signed a $32 million, four-year deal with the Redskins in March 2015 after four years with the San Francisco 49ers.
Culliver has 26 career starts and seven interceptions.
