Miami Heat head coach Erik Spoelstra was an assistant with the U.S. Olympic team that featured a trio of Celtics: Jayson Tatum, Jrue Holiday and Derrick White.

White was the least heralded player on that star-studded, gold medal-winning roster, and the last to be added, coming aboard as a late injury replacement for Kawhi Leonard. But Spoelstra, whose Heat visited TD Garden on Monday for a matchup with Boston, said the versatile guard routinely schooled his big-name teammates with his shot-blocking prowess.

“Derrick is uncanny,” Spoelstra said. “He did it all summer long, too. In practices, I think he got everybody at some point in practice, and in the competitions, he just had a knack for the timely block. It wasn’t just the number of blocks; they were always at the right time.”

White, a second-team All-Defensive selection in each of the last two seasons, is one of the NBA’s premier shot-blocking guards. His 1.1 blocks-per-game average this season ranks first among all players 6-foot-6 or shorter.

“Derrick is really unique,” Spoelstra said. “It’s an incredible talent that he has. It’s a timing (thing), and he’s bigger, longer than most people think that he is. … By now, it’s on everybody’s scouting reports. But if you challenge him, he’s got a way of doing it without fouling.”

White suffered a foot injury last Friday in Chicago and missed Sunday’s loss to Cleveland as a result, but he was cleared to return Monday against Miami. Celtics coach Joe Mazzulla said he would have no restrictions.

In addition to leading the Celtics in blocked shots, White also is on pace for career highs in points per game (18.3 entering Monday), rebounds per game (4.7), 3-point shooting percentage (41.9%) and true shooting percentage (64.1%).
