The Boston Celtics suffered a major loss during their series against The New York Knicks, and it was not the series loss to the Knicks, rather a devastating injury to their franchise superstar, Jayson Tatum.

At 27 years old, Jayson Tatum is already one of the more accomplished players in Boston Celtics history. That's impressive, given the number of Hall of Fame players who have played for the Celtics since the 1950s.

Celtics assistant coach Sam Cassell is optimistic that Tatum will return to his All-Star form after he rehabs from his injury.
