I don't know what happened to Rossi, as I was only tuning into the live timing but I could only deduce that he didn't finish quali to preserve his wrist for tomorrow... did that last race, which is actually a good strategy if you ask me: preserve the wrist, sacrifice the quali then make a come back at the race, rather than get the pole, have a huge pain, and gradually drop at the race tomorrow.
But that's only my opinion.
