LOS ANGELES (AFP) — The Indiana Pacers overcame a scary injury to star point guard Tyrese Haliburton before beating the in-form Boston Celtics, 133-131, in the National Basketball Association regular season on Monday.

Haliburton, one of the brightest stars in the league, was carried off the court by teammates after a painful tumble near the end of the second quarter at Indiana's Gainbridge Fieldhouse Arena.

The 23-year-old grimaced after inadvertently doing the splits as he attempted to change direction while driving towards the basket.

The Pacers later said Haliburton, who did not return to the game, had suffered a left hamstring strain.

With Haliburton out of action, Bennedict Mathurin stepped up with 26 points off the bench to lead the second-half fightback after Indiana trailed 68-59 at the break.

A frantic finale looked to have tilted Boston's way after the Pacers were adjudged to have fouled Jaylen Brown in the closing seconds with the score locked at 131-131.

But Indiana challenged the call and the foul was overturned to leave the score level and give the Pacers one last chance to snatch the win.
