Celtics' Jayson Tatum OK after collision late in win over Heat and expects nothing less in playoffs

The Celtics were winding down a playoff-opening victory, but one of their biggest stars had just hit the floor. All-Star Jayson Tatum, who’d only minutes before notched his first career playoff triple-double, was going up for a rebound under a minute to play when he was undercut by Miami’s Caleb Martin, sending him crashing to the TD Garden surface. Tatum landed hard on his hip but and bounced right up.
