The Boston Celtics beat the Golden State Warriors last night 109-106, ending a 54-game win streak.
Both the Spurs and the Warriors had remained unbeaten at home this season.
Earlier this week, the Spurs topped the 1995-96 Chicago Bulls for consecutive wins. No team, ever, has gone unbeaten at home. The Boston Celtics came close during the 1985-86 season, going 40-1. They won the championship that year.
The Spurs, who take on the Toronto Raptors at home tonight, have a tough road ahead in San Antonio, with games against the Warriors and the Oklahoma City Thunder.
