Griffin missed Monday night's game at Minnesota because of back spasms that he suffered during the first quarter of Saturday night’s game in Houston.
Griffin was at the Clippers’ shootaround Wednesday morning getting up shots.
“I think Blake may play tonight, but I’m not sure,” Rivers said. “But no Jamal for sure.”
Clippers shooting guard J.J. Redick will miss his 25th consecutive game with a bulging disk in his lower back.
The Clippers will play the Dallas Mavericks on Thursday night at Staples Center and Redick won’t play in that game either.
But the Clippers have three home games next week — the Lakers on Sunday, the Oklahoma City Thunder on Tuesday and the Sacramento Kings on April 12 — and it’s possible that Redick could play in one of those games.
“We’ll make a decision [about Redick] then,” Rivers said. “After we get home, our schedule turns after tomorrow’s game [against the Mavericks]. After tomorrow’s game, every game we’ve got two days off [in between games]. So it’s a pretty good schedule.”
