Jalen Brunson scored a game-high 39 points to help the New York Knicks beat the defending champion Boston Celtics 121-113 to take a 3-1 lead in the Eastern Conference semifinals and move just one step away from reaching the conference finals for the first time since 2000.

During the game, Celtics star Jayson Tatum was injured and left the court in the fourth quarter, which made Boston's prospects worse. The six-time All-Star played well in this game, scoring 42 points, but after a turnover in the final quarter, Knicks forward OG Anunoby stole the ball and dunked on a fast break. He fell to the ground in pain while defending and was then wheeled off the court.

Celtics coach Joe Mazzella revealed after the game: "He will undergo an MRI examination and we will wait for the results to come out before making a judgment. The health of the players always comes first. Now we have to worry about his physical condition and consider how to prepare for G5."

The Celtics were in high spirits at the start of the game, with Tatum and Payton Pritchard teaming up to show their strength. At the beginning of the third quarter, Derrick White hit a three-pointer to help the team establish a 72-58 lead. But from that moment on, the Knicks began to fight back.

Brunson gradually took over the game and led the team to overtake 88 to 85 before the end of the third quarter. In the final quarter, he continued to control the rhythm of the game and made consecutive hits at critical moments. Tatum was intercepted by Anunoby in an offense and dunked by a fast break. He fell to the ground injured and was then sent to the locker room.

This round completely destroyed the Celtics' counterattack momentum. At this time, the Knicks had opened the score to 118-106, and the victory was basically determined.

"I just played smoothly, not deliberately dominating the game, just focusing on 'whatever we need to do'." Brunson said after the game, "We didn't give up and kept fighting. This is the most important thing. When you are in trouble, you can't choose to give up."

The Knicks, who are currently leading the series 3-1, will travel to challenge the Celtics. If they can win one more game, they will advance to the Eastern Conference Finals.
