Jon Horst: No decision has been made if Giannis Antetokounmpo will be with Greece for World Cup

“When it comes to our players’ health we always work collaboratively with the player, his representative, and our performance staff to make the best decision possible,” Jon Horst, general manager for the Bucks, told The Athletic. “In the case of national team play, we work with our partners in those federations also. No decision has been made on whether Giannis will be with the Greek national team this summer.”
