The Los Angeles Lakers let a 17-point third-quarter lead slip as they fell to a 127-124 overtime defeat to the Washington Wizards.
The reversal means that the NBA champions have lost three games in a row for the first time this season.
Both LeBron James and Kyle Kuzma missed late three-point attempts to send the game to a second extra period.
Bradley Beal scored 33 points as the Wizards claimed five wins in a row for the first time in three years.
Russell Westbrook, who had 32 points, plus 14 rebounds and nine assists, made a shot inside and was fouled with 11.6 seconds remaining in overtime to put the Wizards up by three points.
Although he missed the free throw which gave the Lakers the chance to tie the score, they were unable to make the shot.
James finished with 31 points, 13 assists and nine rebounds while Montrezl Harrell added 26 off the bench

After an eight-day rest because of two weather-based postponements, the Dallas Mavericks beat the Memphis Grizzlies 102-92 while the Chicago Bulls were too strong for an under strength Houston Rockets, winning 120-100.
