Not saying it happened Sunday, but a sciatic nerve signal will buckle you momentarily. Doesn't even have to 'hurt' that much, just your body shutting muscle signals down for a moment to avoid putting weight on a compromised lower extremity.

Not all that different from the reflex twitch from a hammer tap to the patella.
