American Colin Edwards insists there was nothing he could do to avoid Marco Simoncelli in the crash that cost the Italian his life.
Simoncelli, 24, veered into the path of Edwards and Valentino Rossi at the Malaysian MotoGP on 23 October.
And Edwards said: "I've watched the footage again and I know there is absolutely nothing I could have done to avoid Marco.
"Valentino could do nothing either. It is hard to lose a friend."
Edwards, 37, broke his arm in the crash at Sepang and will be out of action for around four weeks.
He told Italian publication La Gazzetta dello Sport: "We lost a shining star. Marco was loved by all the supporters for his personality, his character, his charisma."
Thousands of fans attended his funeral in his hometown of Coriano, near Rimini.
