The Knicks need one more victory to reach the conference finals for the first time in 25 years. The Celtics need to match the biggest comeback in NBA history to extend their title reign.

Brunson had 39 points and 12 assists, and the Knicks pushed the defending champions to the brink of elimination with a 121-113 victory Monday night in Game 4.

The Celtics will have to make the NBA’s 14th comeback from a 3-1 deficit and may have to do it without Tatum, who was carried off the court with a right leg injury with 2:58 left.

Mikal Bridges and Karl-Anthony Towns each added 23 points and OG Anunoby bounced back from two poor performances by scoring 20 for the Knicks, who can win the series Wednesday night at Boston. If not, they would come back to Madison Square Garden to try to do it Friday night.

Tatum scored 42 points, his high in these playoffs, before he was hurt when the Celtics turned the ball over and his leg gave out as he tried to lunge forward toward the loose ball.

Nobody has come from 3-1 down since Denver did it twice in 2020 at the Walt Disney World resort. It hasn't happened when a team had to win a true road game since Cleveland rallied past Golden State in the 2016 NBA Finals.

Derrick White made six 3-pointers and scored 23 points for the Celtics. Jaylen Brown had 20.
