MILAN -- Giannis Antetokounmpo was held out of Greece's 93-77 win over Great Britain in Monday's EuroBasket game due to knee pain. "He had discomfort in his knee but nothing major," Greece head coach Dimitris Itoudis said at his postgame news conference, adding "we did not want to risk anything so we did not dress him up today." Greece improved to 3-0 in pool play after the win, guaranteeing themselves a spot in the knockout phase of the tournament, which begins Saturday in Berlin. Before missing today's game Antetokounmpo led the Greek squad to hard-fought wins over Croatia and Italy. Itoudis said that he expects Antetokoumnpo to return to action Tuesday against Ukraine. Kostas Papanikolaou and Michail Lountzis each had 10 for Greece, which is now assured of a top-four place in the group. There are four groups with six teams in each at EuroBasket, with the top four finishers in each group headed to the knockout stage. Luke Nelson had 17 points for Great Britain (0-3), while Myles Hesson scored 13, Ovie Soko added 12 and Dan Clark finished with 11. The Associated Press contributed to this report.
