Kevin Durant will undergo an MRI after injuring his ankle prior to his anticipated home debut for the Phoenix Suns on Wednesday.
Durant was ruled out of the game after slipping awkwardly and spraining his left ankle during warmups.
The Suns won 132-101 over the Oklahoma City Thunder in Durant's absence, with Devin Booker scoring 44 points.
Suns head coach Monty Williams was hopeful that Durant had avoided a serious sprain but the All-Star is scheduled for an MRI on Thursday.
"We'll get more testing done tomorrow,” Williams told reporters. "Right now, it's just an ankle sprain and we don't have anything official to report."
Durant was traded to the Suns last month from the Brooklyn Nets and was due to play for the first time as a Phoenix player at the Footprint Center, having played three road games since overcoming a knee injury.
"I feel bad for him because he feels bad," Williams added. "I saw his face and - I've been around him so many times - I know what he's feeling and I don't want him feeling that way at all."
Booker, who continued his hot streak with his fourth straight 35-point game, said the Suns would re-schedule Durant's welcome.
"We'll re-schedule the party," Booker said. "I'm sure they'll be back, people that missed out on tonight. I tried to give them a little something to make it better."
