Miller really was the victim of a strange accident during the Misano 2 Grand Prix: his bike sucked up the tear off film that the riders keep on their helmet visor. And the logo on it clearly indicates the 'culprit', prompting him to publish a funny story on Instagram.

Unfortunately on lap two my bike managed to suck in a tear off was covering the air filter sometimes racing can be a cruel game thanks to my boys for always working there (their) butts off".
