Giannis Antetokounmpo has been ruled out of the remainder of the Milwaukee Bucks' Game 1 against the Miami Heat after suffering a lower back confusion as the result of a heavy fall.

Two-time NBA MVP Antetokounmpo sustained the injury on a drive to the bucket after Kevin Love tried to slide in and take a charge, causing an awkward twisting collision where Antetokounmpo landed flat on his back with 4:13 left in the first quarter.

Antetokounmpo was slow to get back up and attempted to play through the issue, before the Bucks confirmed he was out before half-time.

The Greek forward played for 11 minutes, scoring six points on two-of-four shooting, making two-of-four free-throws, with three rebounds and a turnover.

The Bucks, who have an 11-8 record without Antetokounmpo this season, trailed 68-55 at half-time at Fiserv Forum.

Antetokounmpo has averaged 31.1 points and 11.8 rebounds per game this season, sitting in the NBA's top five for both categories.

Giannis is OUT for the rest of tonight's game with a lower back contusion.
