SAN FRANCISCO (AP) — Jonathan Kuminga suffered a “significant” right ankle sprain and the Golden State Warriors could be without him for an extended period of time, head coach Steve Kerr said.

Kuminga left Chase Center on crutches and will undergo an MRI after landing awkwardly and appearing to roll his right ankle in the paint. He left the game right after with 2:27 left in the second quarter, but the Warriors defeated the Memphis Grizzlies 121-113.

Kuminga, who finished with 13 points and shot 3 of 3 from behind the arc, will almost certainly miss Sunday’s game against the Sacramento Kings.

“It’s a sprained ankle,” Kerr said. “Tomorrow we will have more. It won’t be an everyday thing. It was a severe sprain. So we’ll just have a report tomorrow once we have a better feel for it.”

Kuminga’s injury comes as he is playing the best basketball of his four-year career. He scored 20 or more points in three of his last four games, including 34 points in consecutive games, the highest of his career.

But now the Warriors could be missing their most explosive athlete in some time.

“What crap,” Golden State’s Draymond Green said in the locker room.

Shortly afterwards, Kuminga walked past on crutches. Green asked Kuminga if he was OK, to which Kuminga replied, “Yes, sir.”

The Warriors are already without Brandin Podziemski (abdominal strain) and Gary Payton II (calf). Stephen Curry (bilateral knee injury treatment) also sat out Saturday’s game, which was his first consecutive game.

Curry is expected to play against Sacramento.

“I’m just glad we have the depth that we have,” Kerr said. “I’m glad we have Kyle (Anderson). There was a reason we signed him and Buddy (Hield). That’s why we added a lot of depth to be able to withstand some injuries.”

“It’s going to be hard. JK has been playing the best basketball of his career the last few weeks so we will miss him. But Kyle will fill in well.”
