The Boston Celtics kept themselves in the NBA play-offs with a win against the New York Knicks as the Minnesota Timberwolves beat the Golden State Warriors to reach the Western Conference final.

The Celtics, the reigning NBA champions, were 3-1 down in the best-of-seven Eastern Conference semi-final and missing star player Jayson Tatum, who went off injured in game four and has had surgery on a ruptured Achilles.

However, they earned a convincing 127-102 win at TD Garden thanks to Derrick White's 34 points, and 26 points, 12 assists and eight rebounds from Jaylen Brown.

Game five will take place in New York on Friday at 20:00 local time (Saturday 01:00 BST).

"We made winning plays on both ends of the floor," said Celtics coach Joe Mazzulla. "They made enough plays to win - gave us another chance to play."

The Timberwolves beat the Warriors 121-110 to secure a 4-1 Western Conference semi-final play-off series win.

Julius Randle scored 29 points and Anthony Edwards contributed 22 points and 12 assists for the Timberwolves at Target Center in Minneapolis.

The Timberwolves will play the Oklahoma City Thunder or the Denver Nuggets in the Western Conference final, with the former leading their series 3-2.

"It's great," said Randle. "We've had a season full of adversity. Coach (Chris Finch) said at the end of the regular season that we didn't do anything as far as trades or firing coaches. We just stuck together and we got through it together.

"I'm super proud of our team, everybody that stepped up in some type of way this year. We've got to keep going."

The Warriors did not won a game since losing star player Stephen Curry to a hamstring injury in game one.

"Injuries are part of the play-offs," said coach Steve Kerr. "I learned a long time ago that the play-offs are really about health and then just guys stepping up and making some big shots, big plays in key games. That's what decides every series.

"We've been on both ends of that. There's no sense in dwelling on it, and I don't want to take anything away from what Minnesota just accomplished."
