Milwaukee Bucks star Giannis Antetokounmpo will be sidelined approximately two-to-four weeks with a right calf strain, ESPN reported Thursday.

Antetokounmpo underwent an MRI after sustaining an injury during the first quarter of the Bucks’ 113-109 win over the visiting Detroit Pistons on Wednesday.

After tiptoeing along the baseline and dishing a pass to AJ Green for a layup, Antetokounmpo started to run back on defense when he fell to the floor in the paint. He needed assistance to leave the court with nine minutes left in the opening period.

The nine-time NBA All-Star hit two free throws, grabbed one rebound and handed out the assist to Green before departing.

Antetokounmpo, who turns 31 on Saturday, has struggled to stay on the floor this season. While he is averaging 28.9 points, 10.1 rebounds and 6.1 assists per game, he strained his left adductor muscle on Nov. 17 at Cleveland and sat out the next four games.

Wednesday’s game was his fourth appearance since returning from that injury. He has missed six games this season.
