Anthony Davis suffered his second concussion in just over three years on Monday.
Davis received an inadvertent elbow from Tyreke Evans.
Davis experienced a similar situation in November 2012, when he got hit by former teammate Austin Rivers' elbow on a defensive play in the lane.
The Pelicans did not practice on Tuesday, but before Davis can be cleared to return, he will have to complete a series of tests to determine if he's fit to return on the NBA's strict concussion policy for head injuries.
Since his rookie season in 2012-13, Davis has missed 52 games due to injury that have included two concussions, left ankle sprain, knee soreness, a chest contusion, left toe sprain, abductor strain, right shoulder sprain, fractured hand, back spasms, flu-like illness, right hip contusion, left shoulder soreness and bruised lower back.
