In a film session between Games 4 and 5 of their Eastern Conference semifinal series, as the Celtics prepared for their first game against the New York Knicks without Jayson Tatum, veterans Jaylen Brown and Al Horford challenged the remaining members of the team to rally for their injured superstar.

The notion of losing to a New York team was bad enough, but the sight of Tatum writhing on the floor of Madison Square Garden is branded into the brain of the New England sports mind.

Jayson Tatum's heart-wrenching conversation with his father, Justin, immediately after he went through his Achilles injury, was shared by an NBA insider.

Jayson Tatum appears to be in good spirits after undergoing surgery on his Achilles, giving fans a thumbs up in his first social media post since Monday's devastating injury. Tatum underwent surgery Tuesday in New York after he suffered a ruptured Achilles late in Boston's Game 4 loss to the Knicks at Madison Square Garden on Monday night.

The Golden State Warriors superstar offers some words of encouragement for the injured Boston Celtics All-Star.
