Bucks star Giannis Antetokounmpo is incredibly close to his family. They grew up very poor in Athens and relied on each other — at points Giannis used to have to work selling trinkets during the day to feed the family at night — which is part of why the family was so tight. They remain close, and Giannis — who is very proud he can provide for them — has brought his entire family over from Greece to Milwaukee.

Which is why this news is especially sad: Charles Antetokounmpo, Giannis’ father, passed away Friday from a heart attack at age 54.

“The Bucks family is heartbroken about the sudden death of Giannis’ father, Charles,” the Bucks said in a statement. “The entire organization, his teammates and coaches are here to support Giannis and his family during this incredibly difficult time. Charles was a big part of the Bucks and will be terribly missed by us all. On behalf of ownership, we express our utmost condolences and offer our prayers to Giannis and his family.”
