Isaiah Thomas left the game and immediately retreated to the locker room after turning his left ankle in the fourth quarter of a blowout loss to the Atlanta Hawks on Tuesday. He was diagnosed with a mild left ankle sprain, according to Kristen Ledlow on the TNT broadcast. The Celtics staff claimed it was nothing too serious.

Thomas drove to the lane for a finger roll to cut the Boston Celtics deficit to 29 with 10:25 remaining, but landed awkwardly on his left ankle. He ran gingerly down the court after the play, but committed a foul in order to be taken out of the game. He didn't even stop at the bench, instead running straight to the locker room to be examined.

The Celtics were struggling in Game 5 when Thomas left, falling behind by as many as 31. Thomas had only seven points on 3-of-12 shooting and had dished out three assists. Before Tuesday's game, he was averaging 28.3 points per game in the playoffs.

Thomas will be ready for Game 6, but still a scary moment for the Celtics.
