Giannis Antetokounmpo was as active as he could be during the Milwaukee Bucks' decisive Game 6 win over the Atlanta Hawks. 

Missing a second consecutive game after hyperextending his left knee, the Greek star paced the sidelines throughout the game, exhorting his team-mates on while wearing a mask on his face and a sleeve on his knee. 

Now that the Bucks have advanced to the NBA Finals for the first time since 1974, the key question will be whether Antetokounmpo will be in the lineup for Tuesday's series opener at the Phoenix Suns. 

Bucks coach Mike Budenholzer had no interest in exploring that topic following the win, saying only that it would be an ongoing conversation with the team's medical staff over the next few days. 

"You have to listen to the player and then you have to listen to the sports performance group, and at some point [general manager] Jon Horst and myself are part of the conversations, but it's just a day-to-day thing," Budenholzer told reporters. 

"We'll update it when appropriate. The conversations between he and myself and he and the sports performance group, it's kind of private and we'll see where he is each day."

Despite the ongoing questions about Antetokounmpo's availability in the Finals, Budenholzer took time to appreciate his star's enthusiasm even when he is unable to take the court. 

"He's coming off the bench, he's halfway on the court, talking to Bobby [Portis], talking to Brook [Lopez], talking to different players; to see that kind of leadership, that kind of connection, that kind of commitment from a player you know would be dying to be out there and playing," Budenholzer said.

"I just loved his energy on the bench. I loved his just togetherness that he brings to our group.

"And there's a bittersweetness to him not being able to play these last two games, but I think he understands that there's a way we want to play basketball and there's a kind of team and organisation that we want to be able to play and just play ball, and he's a big part of that.

"But if he were to miss a game or if he's on the bench for whatever reason, we need to be able to play and we need to have guys that have confidence and we need to be able to get stops and do all the things that go into winning.

"While he's incredibly important to us, I think he appreciates what his teammates can do. And we certainly do as an organisation appreciate what he did, and then what everybody else was able to do tonight and the other night without him."

Saturday night, it was Khris Middleton's 32 points and Jrue Holiday's 27 that ensured Antetokounmpo would at least have a chance to return. 

Even if Antetokounmpo is not ready to open the series against the Suns, his team-mates appreciated the effort he gave on the sidelines tin Game 6.

"This is probably the most I've seen Giannis talk, like the whole game," Holiday said. "I know usually when he's on the court and he's running, racing through five people and blocking shots, you're tired. He's tired and he's playing.

"But man, he's motivating everybody, he's motivating me, telling me to push the pace, telling me to keep being aggressive and telling me to lock people up.

"I feel what he brought to the game today and how he led us - again, he is pretty quiet, but how talkative he's been has been awesome for us and very, very encouraging."
