The Indiana Pacers appeared to have a Game 1 upset in hand.
Jaylen Brown had other ideas.
The Boston Celtics All-Star stunned the Pacers with a 3-pointer in the final seconds of regulation to tie Tuesday's Game 1 of the Eastern Conference finals at 117-117. The game then went into overtime, where the Celtics prevailed, 133-128 to take a 1-0 series lead.
The Pacers led, 115-110 late and appeared to be in control with the ball and a 117-114 advantage with 10 seconds left in regulation. But they turned the ball over on a sloppy inbounds pass to breath new life into the Celtics.
