Kyrie Irving drove the length of the floor and banked in the game-winning layup with four seconds remaining as Cleveland defeated Denver, 100-99. Antawn Jamison scored a game-high 33 points to go with nine rebounds and Irving finished with 18 points and eight assists for the Cavaliers, who snapped a six-game skid.  Alonzo Gee netted 19 points in the win.  Al Harrington paced the Nuggets with 22 points and Ty Lawson had 18, though he failed to convert a field goal attempt that would have won the game for the Nuggets, who saw a four-game winning streak end.  Nuggets center Nene  started for the first time since missing 10 games with a calf injury.  He had 13 points in the loss.
