The Thunder may be missing two guards against the Warriors Sunday.

After practice Saturday, OKC coach Billy Donovan ruled out Andre Roberson (return to play management) for Sunday’s game. The Thunder plans to determine the availability of Hamidou Diallo (left ankle) just before the game, Donovan said.

Diallo suffered a left ankle injury during the Thunder’s 97-85 loss to the Wizards Friday, but he remained in the game. Diallo did not practice Saturday, according to Donovan.

“We’ll have to see where he’s at,” Donovan said. “I think we’re hopeful that he can play tomorrow, but I think we’ll have a better idea right around game time. We’ll see how he responds to some treatments today.”
