Per Boston.com:
On Monday night, a rowdy and fervent TD Garden crowd was quickly quieted.
Jayson Tatum, the Celtics’ star player, collapsed to the parquet floor in agony just 34 seconds into a critical Game 7 versus the Heat.
Tatum rose to his feet and rolled his ankle on the landing while attempting to euro-step past Miami point guard Gabe Vincent.
Even though the All-NBA forward continued to play, the damage had already been done.
“I saw the video, I saw it after the game that I came down on my ankle. It’s tough, because it kind of impacted me the rest of the night,” Tatum said following Boston’s season-ending 103-84 loss to the Heat. “It swelled up and it was just frustrating that I was kind of like a shell of myself. It was tough to move. It was just frustrating, especially that [expletive] happened on the first play.”
