New Orleans Hornets rookie forward Anthony Davis suffered a stress reaction in right foot, Coach Monty Williams announced before Tuesday night's game against the New York Knicks.
Williams said this season's first overall draft pick would miss Tuesday's game and is listed as day-to-day.
A stress reaction is an injury to the bone that, if left untreated, could be the precursor to a stress fracture.
Williams said the Hornets would carefully monitor Davis' recovery. The Hornets initially had characterized his condition as a left ankle injury.
The Kentucky product has averaged 16 points and 8.5 rebounds in six games for the 3-5 Hornets. He has missed two after suffering a concussion.
