Griffin didn’t play in the last two exhibition games because of what the Clippers called a “sore right ankle.”
The Clippers play Saturday night in Las Vegas against the Denver Nuggets.
“He’ll probably play Saturday ... but if he’s not 100%, no, he won’t play,” Rivers said. “I’m not going to play him unless he’s 100%.”
Griffin injured his ankle Saturday night against the Utah Jazz. He returned to play in the second half of that game.
The Clippers All-Star power forward also suffered a bruised bone in his left knee last Wednesday night during the team’s intrasquad scrimmage.
After getting an MRI, Griffin missed one day of practice before being cleared to practice.
Now he's dealing with the ankle injury.
“It’s just precautionary. He sprained his ankle,” Rivers said. “There is no reason to take a chance now. I want him to start the season healthy.”
Rivers got sick at halftime of the Clippers’ game in Phoenix on Tuesday night.
But he was at the Clippers’ Charity Golf Classic at Trump National Golf Club on Wednesday.
“I’m good. I just wanted [assistant coach] Alvin [Gentry] to get a chance just in case something ever happened,” Rivers joked about Gentry, who was fired as coach of the Suns last season. “But I am good.”
