I've had a similar crash to his before, where I've gone over the bars and somersaulted, and didn't get concussion. I think teams are very aware of this and will have checked him yesterday and probably again today, but not every accident leads to concussion.
Yeah - it was a mechanic I think. I'm sure they've had some training but shouldn't be making a major decision. Tough in bike racing cos you can't fuck about for 5 mins. I'd hope and expect the team/race medics did some protocols on him once back on the bike and patching him up.
