Antetokounmpo was defending a jam by Hawks center Clint Capela with 7:14 remaining in the third quarter when his left knee appeared to buckle. He fell to the floor in obvious pain, grimacing and clutching his knee.
Bucks coach Mike Budenholzer said the team would learn more about Antetokounmpo’s status on Wednesday.
“We’ll take everything as it comes,” Budenholzer said. “We’ll evaluate it. We’ve got a heck of a team, a heck of a roster. … The guys will prepare. They’ll be ready.”
Antetokounmpo remained down for several minutes before rising and slowly walking to the locker room. He was supported by his brother, Thanasis Antetokounmpo, and a staff member, as he left the court.
It was a scary sight — and sound — for the Bucks.
“I heard him yell,” Khris Middleton said.
Added Jrue Holiday: “I think just based on how he was grabbing his leg, it seemed like it was pretty bad.”
Giannis Antetokounmpo returned to the bench briefly before again heading to the locker room after the Hawks blew open the game by extending their lead to 20 points. Soon after, the Bucks announced he would not return.
“I don’t want to speak for him,” Budenholzer said when asked what Antetokounmpo told his teammates when he briefly returned to the bench. “I know historically it’s impossible to keep him off the court, keep him away from his teammates. My guess is he wants to play and, if not, let his teammates know that he’s there for them.”
Following a slow start to the game, Antetokounmpo had scored eight of his 14 points in the opening minutes of the second half. Following the jam by Capela, the Hawks led 62-52 when the Bucks’ star left the game.
The loss of Antetokounmpo appeared to derail the momentum of the Bucks’ comeback.
Holiday said the injury wasn’t a distraction.
“No. We’ve been around the game long enough to know guys are going to get hurt,” Holiday said. “You pray it’s not serious.”
Budenholzer said Antetokounmpo is “a big part of our soul and our fiber. I’m sure the human element and the concern is real. They’re trying to find a way to be there for him when he’s not on the court.”
The Hawks were without their leading scorer, Trae Young, who was held out with a bone bruise in his right ankle.
