Davis was held out of Saturday's 112-110 loss to the Minnesota Timberwolves and did not participate in Pelicans practice on Monday, according to Gentry.
"He's fine, I think," Gentry said. "We're expecting him to play. Obviously kept him out of practice today. But everything seems to be OK. He'll be a game-time decision. I'm anticipating him playing."
Davis was observed working on his jump shot with assistant coach Kevin Hanson at the conclusion of Monday's practice.
"Nothing wrong with his shot," Gentry said. "We just got to make sure he can run up and down. Which, like I said, I anticipate him being able to do that."
The 22-year-old All-Star has missed seven games this season (the Pelicans went 1-6). He has also been held to 20 minutes or fewer just five times this season (the Pelicans went 2-3).
Davis has missed 14 games or more in each of his previous three NBA seasons.
The Pelicans have already lost Tyreke Evans (right knee surgery), Quincy Pondexter (left knee surgery) and Bryce Dejean-Jones (right wrist surgery) for the season, and Omer Asik is expected to miss two weeks after spraining his right ankle Sunday in Detroit.
Davis is averaging 24.2 points, 10.2 rebounds and 2.2 blocks per game with a 25.63 player efficiency rating this season. His real plus-minus of 3.31 ranks sixth among NBA power forwards.
