Golden State Warriors forward Kevin Durant, who sat out Sunday night's 118-111 win over the Brooklyn Nets with a left ankle sprain, told ESPN's Chris Haynes that he's "not sure" whether he'll be able to play Wednesday at Oklahoma City.

"I'm just going to take it day by day and see how it progresses," Durant said before the game.

Wednesday would mark the second time Durant plays the Thunder after leaving them as a free agent in 2016.

Durant said he sprained his ankle in the first few minutes of Saturday night's win over the Sixers.

Warriors coach Steve Kerr said he was uncertain whether Durant would be available Wednesday.

"Two days should give him a chance to heal and be fine for Wednesday," Kerr said. "It makes sense to give him tonight off."

Reserve guard Omri Casspi will start in Sunday's game against the Nets.
