Disagree. The protocol failed. There was no sign of head trauma. He was not hit hard in the head. There were no signs of Anoxia. He was just slow to get up but there are many reasons why that could happen on a football field that do not include head trauma. He was coming off an ankle injury and the hit had much more of an impact on his lower body. He never had a concussion at any time before, during, or afterwards. When the rule states the ref taking someone off the field for a head injury means they are out for the game, that ref needs to be much more certain when making that call.
