Test results on Tuesday showed no structural damage to the knee, according to the Clippers.
Griffin was injured in the final minutes of a Clippers victory over the Los Angeles Lakers at Staples Center on Monday night when he and teammate Austin Rivers collided in pursuit of a loose ball.
Griffin remained in the game on the ensuing Clippers possession, during which he missed a 10-foot hook shot. He ultimately checked out of the game and retreated to the Clippers' locker room after a layup by Lakers forward Brandon Ingram and a Clippers timeout. Griffin left the locker room without speaking to reporters.
Griffin has averaged 23.6 points and 7.9 rebounds a game this season.
Griffin, a five-time All-Star, signed a five-year, $173 million maximum contract extension in July to remain with the Clippers.
He has sustained several serious injuries through the years, including season-ending toe surgery after Game 3 of the Clippers' first-round loss to Utah in the Western Conference playoffs last season. Griffin had missed 18 regular-season games after knee surgery.
The Clippers have been riddled with injuries this season, including season-ending microfracture knee surgery to starting point guard Patrick Beverley. Two more starters -- guard Milos Teodosic and forward Danilo Gallinari -- are sidelined for extended periods.
The Clippers are 8-11 and have posted three straight victories.
