But the biggest loss may have been their All-NBA superstar, Jayson Tatum, who suffered a torn Achilles in Game 4 of the second-round series against the New York Knicks. This ended the rest of his playoffs and has put the upcoming season in jeopardy. The Celtics went on to lose to the Knicks in six.

Jayson Tatum reportedly is making strides in his rehab from a torn Achilles injury. Per Heavy Sports' Steve Bulpett, one scout said the Boston Celtics star looks "way ahead" in his recovery.

Nearly three months removed from a season-ending Achilles tear during Game 4 of the Eastern Conference Semifinal, Boston Celtics star Jayson Tatum is beginning his road to recovery and no longer wearing a boot on his surgically repaired right ankle.
