Pramac Ducati's Jack Miller broke his collarbone and suffered a rotator cuff tear in a mountain bike crash before the Austin MotoGP round but still managed to finish in ninth place - two ahead of Jorge Lorenzo on the factory GP18 - yesterday.
Miller kept the injury quiet over the Texas weekend but admitted afterwards he had been training in California and crashed - but was lucky a fall in free practice didn't aggravate the injury.
"I expected more coming into the weekend, but we struggled with the bike set-up from the get-go, and I was struggling with a shoulder injury that I carried into the weekend as well. Not ideal," said Miller.
"We kept pretty quiet about the shoulder all weekend, but now we're done, I can admit that it wasn't great. I was out training in California after Argentina, and I fell off doing some mountain biking.
"The injuries are nothing that some rest time and recovery can't handle, but I ended up with some muscle damage, some bruising and a little tear on my rotator cuff on my right shoulder. And a crack in my collarbone as well.
"I tell you, sometimes the time between the races can be more dangerous than the race weekends themselves."
