I can't explain the debacle any better for you, but I'll add in another aspect of "WTF?".
It's not surprising that the UCI decided to try and deflect any blame, and released a statement right after the injury report saying they were following all protocols, blah blah. But they never once reached out to Brook after the crash or during his recovery. Not even a conversation to see how he's doing, or even capture any information regarding the incident. Mind boggling.
