Superstar power forward Giannis Antetokounmpo injured his right knee in the first quarter of the Bucks’ 128-99 win over the Miami Heat on Friday night.

With just over a minute to go in the first quarter, the two-time NBA MVP took a knee with another player. Antetokounmpo was unable to return to the game.

Bucks head coach Mike Budenholzer said he wasn’t sure exactly when Antetokounmpo hurt his knee, but noted that he would be considered day-to-day due to the injury.

Antetokounmpo entered the game with a nagging wrist injury sustained in a game before the All-Star break. He started in last week’s All-Star Game but exited quickly after scoring just two points.
