Kyrie, Harden out for Game 5 vs. Bucks
Irving reportedly underwent an MRI, and Nash said he has "no idea" whether the guard will play again in the Eastern Conference semifinals, according to ESPN's Malika Andrews.
James Harden will also sit out Game 5. Harden has missed all but the opening 43 seconds of Game 1 with hamstring tightness.
With Irving and Harden both sidelined, Kevin Durant knows he'll have an even larger role to fill as Brooklyn's only healthy star in Game 5.
"I picture me doing everything out there just like any night," Durant said, according to Forbes' Adam Zagoria.
Brooklyn and Milwaukee enter Game 5 with the series tied 2-2.
