A packed TD Garden crowd held its collective breath on Sunday as Jayson Tatum writhed in pain on the parquet floor.
Down the other end of the court, Celtics head coach Joe Mazzulla had a far different reaction as his best player nursed his ailing wrist.
In a clip that has now gone viral on social media, cameras caught Mazzulla yelling at Tatum to “get up” while holding back a trainer. Tatum — who hit the court hard after getting fouled by Orlando guard Kentavious Caldwell-Pope while going up for a dunk — eventually got back on his feet en route to a Game 1 blowout win over Orlando.
