Giannis Antetokounmpo joined the Milwaukee Bucks training camp for the first time on Saturday after recovering from COVID-19 in Greece.
Antetokounmpo participated in non-contact work, according to Doc Rivers.
"He said he's going to need a good three days," Rivers said.
Antetokounmpo said that he was still recovering from a physical standpoint.
"I think it took a toll on my body. I'm not feeling 100 percent yet physically," Antetokounmpo said. "Just taking it day by day, getting back in shape. I was able to do some 5-on-0, run up and down a little bit. Tomorrow I'll be a little better."
Rivers added that Antetokounmpo's absence gave the team an opportunity to play without him.
"The key to our team every year is the minutes when Giannis is off the floor," Rivers said. "So, we've been working on that. And so maybe that'll help us in the long run."
