Just like every other player that experiences a concussion of any degree Olave went through the league's concussion protocol which requires as a final of five steps being "cleared by both the club physician and the independent neurological consultant to return to full activity". From what I have heard that basically means it has been determined that the player is subject to no greater danger than any other player playing the same position.

The player is more aware of any risk and is in a better position than any of us to weigh any risk. Playing in the NFL is risky for every player. That's one major reason why they get paid as much as they do. Let's not forget that these players have committed their entire lives to the privilege of playing in the league.
