Giannis Antetokounmpo and the Bucks have started the season with a record of 1-5. 

CLEVELAND (AP) — Milwaukee superstar Giannis Antetokounmpo will miss Monday night’s game against the unbeaten Cleveland Cavaliers with a strained adductor muscle, another early season hiccup for the struggling Bucks.

Coach Doc Rivers said Antetokounmpo went through morning shootaround before the team decided to give him the night off. Rivers said he was already opting to sit the two-time NBA MVP before the medical staff gave its opinion.

Rivers said isn’t sure when Milwaukee’s best player got hurt. He noted that Antetokounmpo hates to miss any games, and especially with the Bucks off to a shaky start. Milwaukee has lost five straight.

“I had decided in my own mind that he shouldn’t play tonight right when they told me he that he was sore (Saturday),” Rivers said. “I was happy when they said — not happy because you want him to play — but for his health I think it’s the right thing.”

Antetokounmpo is averaging 31 points pfor the Bucks, who are just 1-5 and lost by one point at home to the Cavs on Saturday.

By sitting out, Antetokounmpo will have four days to rest before the Bucks host Utah on Thursday.
