MIAMI GARDENS, Fla., Dec. 22 (UPI) -- Kader Kohou left his feet for a game-sealing interception, helping the Miami Dolphins preserve a late lead over the San Francisco 49ers and keeping their razor-thin playoff hopes alive Sunday at Hard Rock Stadium. Kohou's clutch catch came with about two minutes remaining in the 29-17 triumph in Miami Gardens, Fla. Seconds later, running back De'Von Achane ran for a 50-yard touchdown.
