Two points:
1. ESPN article saying that George told the Pacers docs that he was fine and only confessed to blurry vision and a hurting head later, plus the NBA said that the policy was followed:
2014 NBA playoffs -- Paul George of Indiana Pacers says he's symptom-free after concussion - ESPN
2. Kornheiser and Wilbon from their PTI show note in the video on the same page as the above story that the NBA policy was NOT followed as George was not taken to a quiet place to be examined. He was questioned on the bench during the TO.
Lastly, who couldn't tell that this player was unconscious? That should have triggered a serious examination and return-to-play protocol.
