Kelly Oubre Jr. lost a playoff game Monday night and then he lost his beloved car ... TMZ Sports has learned he wrecked his Lamborghini in a crash just hours after the Sixers fell to the Knicks in Game 2 of their postseason series.
The Philadelphia Police Dept. tells us the wreck happened at around 1:45 AM on Tuesday ... shortly after Oubre and the 76ers dropped a heartbreaker at Madison Square Garden, 104-101.
Cops say Oubre's 2021 matte purple Lambo "disregarded a red traffic signal" .
