Miami, Florida/New Orleans, Lousiana - Luka Dončić scored 42 points with 10 rebounds, but it was not enough for the Dallas Mavericks who suffered their sixth NBA loss from their past seven games 129-122 to the Miami Heat on Saturday.

The win was much needed for Miami, who improved to 41-37 to be seventh in the East, with Jimmy Butler top scoring with 35 points and 12 assists at FTX Arena.

The Heat snapped their three-game skid but it left the Mavs' perilous playoff hopes worse off, falling to a 37-41 record, remaining 11th in the West.

Dallas are a game back from Oklahoma City (38-40) in the race for the final play-in spot, with the Thunder owning the head-to-head tiebreaker too.
