I know that they said it was a stinger, but he did pass out.

I've had a stinger before and it hurts like hell. You can't move at all and you feel like chopping that area off.

However, when he went down to the ground, that didn't look like he was just hurt. It looked like he fainted or passed out, which would really lend itself to concussion symptoms. I certainly hope that he is alright. If anyone has any info, shout it out.
