Donovan Mitchell will miss Game 1 of the Utah Jazz's Western Conference first-round series against the Memphis Grizzlies due to an ankle injury.

Mitchell has been sidelined since spraining his right ankle on April 16 and the NBA All-Star was ruled out of Sunday's playoff opener having expected to face the Grizzlies.

Jazz guard Mitchell has missed the past 16 games for Utah, who clinched sole possession of the best record in the NBA for the first time in their history after finishing 52-20 in the west.

Mitchell has been averaging career highs in points (26.4), assists (5.2) and three-point percentage (38.6) this season.

The Grizzlies won through to the playoffs after eliminating the Golden State Warriors in overtime in Friday's play-in game.
