The NBA isn't exactly known for having concussion issues, but that was until this year's Western Conference Finals when the Splash Brothers of the Golden State Warriors brought to light the issue in successive games.

And now, the NBA Players Association has hired neurologists to examine the league's concussion policy and determine whether changes are in order to prevent players from playing with an undiagnosed concussion.

In Game 4 of the WCF, Steph Curry bit on a Trevor Ariza fake, which caused him to clip his legs on the Rocket's legs and slam his head against the floor. He was diagnosed with a contusion, and was allowed to return to the game.

A couple of nights later, Klay Thompson took a knee to the head after his own head fake, was cleared to return to action, but was diagnosed with a concussion a couple of days later.

"It mortified me," NBA Union chief Michele Roberts said.

Adding, "That number is sufficient enough to make us all look at whether we want to risk a player's health for a game. To say it happens so rarely or doesn't happen frequently enough to change the rules is not enough. We're talking potentially about someone's life. I don't think we should play an odds game when it comes to a player's life."

As noted by FOX Sports, the director of the league's concussion program, Dr. Jeffrey Kutcher, said the Warriors handled both instances properly in spite of Thompson being cleared to play before being diagnosed later with a concussion. Kutcher points out that about 25 percent of concussions don't show symptoms until hours, or even a day after the hit.

According to the FOX Sports report, the NBA has averaged 13 concussions a season over the past four years since the protocols were installed. In comparison, the NFL reported 111 in the 2014 regular season alone, with the number jumping to 202 when including preseason and practices.
