CHICAGO (AP) --

New Orleans Hornets coach Monty Williams blasted the NBA's protocols for determining when a player can return from a concussion, a day after No. 1 draft pick Anthony Davis suffered a mild one.

Williams unloaded before Saturday's game against the Chicago Bulls, saying the league is treating "everybody like they have white gloves and pink drawers." He says it's "getting old"

His comments came on the heels of Davis leaving Friday's win over Utah after taking an inadvertent elbow to the head from teammate Austin Rivers in the first half. A Chicago product, Davis stayed back in New Orleans to be examined and did not accompany the team on the trip.

He cannot return until he completes a series of tests to determine if he's fit to play.
