Dallas Mavericks superstar Luka Doncic exited in the first quarter of Thursday's game against the Phoenix Suns due to a sprained left ankle.
Doncic suffered the injury when he stepped on a Suns defender's foot while pivoting a few minutes into the game.
Dallas called a timeout with 8:39 remaining in the first quarter to substitute for Doncic, who immediately limped to the locker room along with Mavs director of player health and performance Casey Smith.
The Mavs announced at the conclusion of the first quarter that Doncic would not return to the game.
