However, the NBA has now announced that Tatum traveled on the final play. Via Bleacher Report: "L2M report says Tatum slid his pivot foot 'before releasing his dribble' on his game-winning shot vs. Raptors 😮 The report also says the Raptors should've been called for a foul after making contact with Jaylen Brown prior to Tatum's shot" The Celtics still won the game,

Tatum moved his pivot foot with 3.4 seconds left in overtime and should have been called for traveling, but an earlier missed call would have rendered that moot.

Jayson Tatum traveled moments before making the deciding 3-pointer at the overtime buzzer to give the Boston Celtics a 126-123 victory over the Toronto Raptors, the NBA said.
