Giannis Antetokounmpo was ruled out again for the Milwaukee Bucks ahead of Saturday's Game 3 in their NBA first-round playoff series against the Miami Heat, reports said.

Battling a bruised lower back, which he suffered in the series opener, the two-time NBA MVP had to miss the second game and remains on the injured list.

The Bucks had listed Antetokounmpo as doubtful on Tuesday after an X-ray and MRI scan both came back clean, and the problem has not gone away.

The Greek forward averaged 31.1 points and 11.8 rebounds per game during the regular season, sitting in the NBA's top five for both categories.

Without Antetokounmpo, the Bucks drew level in the seven-game series by winning 138-122 on Wednesday.
