Victor Wembanyama scored 34 points as the San Antonio Spurs stunned the Denver Nuggets to open up the race for top seed in the Western Conference.
Denver knew two wins from their final two games would secure top spot and home advantage in the play-offs.
But their defeat plus wins for the Minnesota Timberwolves and the Oklahoma City Thunder leaves the trio level.
It is the first time in NBA history there has been a three-way tie for top spot with one game left.
Wembanyama, 20, added 12 rebounds, five assists and two blocks, while Devonte’ Graham hit the deciding jumper with 0.9 seconds left on the clock to seal victory.
Despite the win, San Antonio remain level with the Portland Trail Blazers at the foot of the Western Conference.
At the top, Oklahoma City beat the Milwaukee Bucks 125-107 while Minnesota were 109-106 winners against Atlanta.
Oklahoma City lead the Conference because of their superior head-to-head record between the other two sides, with Minnesota second and Denver third.
The only way Denver can regain top spot is if both Oklahoma City and Minnesota lose in their final games on Sunday.
