He was thrown off the raft after we landed on a rock and he was sucked under a rock in front of us and if it hadn’t been for the water pressure pushing him away from being under the rock he would’ve drowned down there. When he got out he seemed to me like he was out of it and later confirmed to me that he had hit his head on a rock under the water and was briefly unconscious when he surfaced. After speaking with him recently I found out he injured his wrist, had a concussion and several major bruisings on his legs and feet. As of today he has is very sore but should make a full recovery.
