New Orleans Pelicans All-Star power forward Anthony Davis has an upper respiratory infection and did not play against the Toronto Raptors on Wednesday night, Coach Monty Williams said.

Williams had said in his pregame media interview that Davis' availability would be a game-time decision. He said then that Davis may have the same illness that knocked guard Eric Gordon and guard/forward Tyreke Evans out of the Pelicans' game March 12 against the Memphis Grizzlies.

“Anthony is not feeling too good,” Williams said before checking with head trainer Jon Ishop. “We've had a couple of our guys who have been under the weather, so I'm going to get back (in the training room) and talk to (head trainer John Ishop) and see if all of our guys are ready to go.”

Davis is coming off a game Sunday against Boston in he had 40 points, 21 rebounds and three blocked shots, the first time in franchise history that has been accomplished and one of the few times in NBA history. He has averaged 32.3 points and 14.3 rebounds during the past six games, as the Pelicans have gone 4-2.

It is the ninth game he has missed his season. Rookie center Jeff Withey took Davis' place in the starting lineup alongside center Greg Stiemsma. Withey played a career-high 29 minutes, 3 seconds against Boston and tied his career high with three blocked shots. He also had five rebounds – two offensive – and two points.

This is his first start of the season.

Raptors coach Dwane Casey said starting center Jonas Valanciunas and power forward Patrick Patterson also will miss the game. Valanciunas has a sprained lower back, and his absence was expected after he fell hard in Tuesday's game at the Atlanta Hawks. Valanciunas, who is from Lithuania, is known for being a strong, physical presence.

Patterson, like Davis a former Kentucky standout, has a right ulner collateral sprain.
