Greece's 93-77 win over Great Britain in Monday's EuroBasket game was delayed because of knee pain for one of the players.
"He had some pain in his knee, but it was nothing major, so we didn't dress him up today," Greece's head coach said after the game.
After the win, Greece secured a spot in the knockout phase of the tournament.
Antetokounmpo led the Greek squad to victories over Croatia and Italy. Antetokounmpo is expected to return to action on Tuesday.
Greece is assured of a top-four place in the group thanks to the efforts of Kostas Papanikolaou and Michail Lountzis. The top four teams from each group will advance to the knockout stage.
Ovie Soko and Dan Clark both had 11 for Great Britain.
