This tells a lot of the tale right here. Rossi hit the paint area under braking and lost the rear end a bit. Wickens didn't make enough of a block earlier and/or probably should have let Rossi overcook the corner. Just a tough racing deal.
I doubt it, with the suspension damage he sustained, but they might let him fix it overnight and go out there one or two laps down. Can't find anything definitive.
I was reading the rule book. Based on his tweet I guess if a race is postponed the red flag is still in effect.
