Boston Celtics are in distress as Jayson Tatum suffered a lower leg injury during Game 4 against the New York Knicks. Al Horford expressed deep concern for Tatum, emphasizing his importance to the team and Boston.

The Boston Celtics suffered a tough Game 4 loss to the New York Knicks in the Eastern Conference semifinals, but the biggest loss of the night may have come when Jayson Tatum injured his leg during the fourth quarter.

NBA insider Brian Windhorst reported for ESPN, "Even if Horford doesn't re-sign -- he doesn't plan to retire and would like to return, sources said -- Boston is facing a payroll, with luxury taxes, next season of $464 million, according to ESPN front office insider Bobby Marks."

The Celtics again collapse late in Game 4 against the Knicks — but Jayson Tatum’s uncertain lower leg injury overshadows the game’s outcome.

The NBA world quickly reacted to the seemingly devastating injury to Jayson Tatum late in the Knicks’ win over the Celtics in Game 4 on Monday night.

On the strength of a 39-point performance by Jalen Brunson, another fantastic fourth quarter from Mikal Bridges and by far their best offensive showing of the series, the New York Knicks took a 3-1 series lead against the Boston Celtics with a 121-113 win in Game 4 on Monday at Madison Square Garden.

Jayson Tatum is one of the most accomplished players in the NBA. He finally got the monkey off his back last year by winning his first NBA title. That hasn’t stopped people from criticizing him, though,
