The Milwaukee Bucks will receive a huge boost for Monday's Game 4 against the Miami Heat as two-time MVP Giannis Antetokounmpo returns from a two-game injury absence.

Antetokounmpo missed Game 2 and Game 3 after suffering a hard fall early in Game 1, resulting in a back contusion.

After dropping the series opener, the Bucks responded with an emphatic Game 2 victory at home to tie things up, before the Heat jumped ahead 2-1 with their Game 3 triumph in Miami.

Antetokounmpo finished the regular season top-five in both scoring (31.1 points per game) and rebounding (11.8 rebounds per game), and his return will be an enormous boost for the Bucks, who posted the best record in the league at 58-24.

Speaking before Monday's game, Bucks head coach Mike Budenholzer declared his star "ready to go".

"We'll keep our eyes on him like we do really all our guys, but there's been nothing put on him from medical or anything like that," he said.

Heat coach Erik Spoelstra responded to the news by saying it will be a significantly tougher test with Antetokounmpo in the line-up, but he wants the Bucks at full strength.

"You can do all the prep behind the scenes but [Antetokounmpo] is going to bring it at a different level of physicality and force than what we can cover in a practice," he said.

"We have great respect for him and what he can do... when you get in the playoffs, you want everybody available."
