Hit his head hard, but doesn’t mean he absolutely had a concussion. His eyes looked fine, no change in his gait once he got up. Other players have had that blank state when concussed, Josh didn’t. I’d be surprised if he didn’t have a concussion after that TBH, but he was cleared.
As for the smelling salts? Josh has used them for years. I think he made a comment about them at one point, can’t recall what he said. There was. TBD thread on it.
