Big performances from James Harden and Russell Westbrook saw the Houston Rockets snatch a 153-149 comeback victory over the Dallas Mavericks.
Harden scored 49 points but looked to have lost it for the Rockets after missing a free throw with 3.9 seconds left and Houston down 139-136.
Luka Doncic finished with a triple-double for the Mavericks before Robert Covington emerged to push a tip-in home and tie the score, forcing overtime which Houston won, with Harden scoring seven of the team's next 14 points.
