Davis sustained the injury Friday in the first quarter of a home loss to the Indiana Pacers. He leapt over the first row of fans in an effort to save the ball from heading out of bounds, and he landed hard on his back. X-rays taken soon after the game came back negative.
"It was one of those freak things where he fell and got a bruise there. It's no big deal," New Orleans coach Alvin Gentry said. "It was a pretty good fall. Maybe if it was a playoff game, we'd stick him out there. I just don't see a reason to risk anything or him try to overcompensate. We'll see what happens tomorrow night."
This will be the fifth game Davis has missed this season. He is averaging 22.8 points, 10.8 rebounds and 2.5 blocks per game for the 11-25 Pelicans. Since being drafted No. 1 out of Kentucky in 2012, the 22-year-old has yet to play more than 68 games in any of his three seasons.
The Pelicans face the Kings on Wednesday in Sacramento.
