Knicks vs Celtics Game 4: An Unforgettable Battle

Game 4 on May 12, 2025, was nothing short of intense. The Celtics jumped out to a double-digit lead, but the Knicks, led by the ever-consistent Jalen Brunson, fought back fiercely. Brunson tallied 39 points and 12 assists, particularly dominating in the third quarter with 18 points. Despite star performances from Jayson Tatum—who notched 42 points before leaving with a severe right leg injury—the Celtics couldn’t hold their advantage.

Tatum's Injury and What It Means for Boston

The game’s atmosphere shifted dramatically when Jayson Tatum collapsed late in the fourth quarter. He was helped off the court, later diagnosed with a ruptured Achilles tendon. This injury not only ended his night but also casts doubt on the Celtics’ playoff hopes moving forward. According to NBC Sports Boston’s update, Tatum underwent successful surgery, but recovery times for such injuries often stretch close to a year.

Boston’s ability to bounce back now hinges on players like Jaylen Brown and Derrick White stepping up in the absence of their leader.

Key Players and Turning Points

Jalen Brunson’s leadership was unmatched down the stretch, but he wasn't alone. Mikal Bridges and Karl-Anthony Towns each added 23 points, while OG Anunoby contributed 20. The Knicks' fourth-quarter 11-0 run proved decisive and displayed their collective resilience. On the Celtics’ side, Derrick White impressed with six three-pointers and a 23-point night; Jaylen Brown pitched in 20 points, though added foul trouble late in the contest.

The series’ momentum now belongs to New York, but Boston remains alive as the matchup returns to TD Garden.
