Portland Trail Blazers forward Al-Farouq Aminu left Wednesday's 112-103 overtime loss to the Utah Jazz with a right ankle injury.
Aminu rolled his ankle going for a rebound in the second quarter. He limped to the bench after the play.
X-rays taken at Vivint Smart Home Arena in Salt Lake City were negative. He was diagnosed with an ankle sprain and had a walking boot on as he left the facility with the team.
"It's just always annoying not being 100 percent," Aminu said after the game. "It's a part of the game and everything happens for a reason. It's hard to sometimes to see the light at the end of the tunnel, but you know it's there."
In seven games so far this season, Aminu has averaged 9.6 points and 8.4 rebounds.
"It's tough," Blazers point guard Damian Lillard said. "Chief [Aminu] is a huge part of our team. He does a lot of things that might not get mentioned all the time, might not show up on the stat sheet, but he's as big a part of our team as just about anybody.
"Whatever the situation might be, somebody's going to have to step up, and we're going to have to figure out a way to get some wins."
