Cal Crutchlow crashed out of the Gran Premio d'Italia.
The Coventry born Ducati rider went down with his bike hitting Stefan Bradl as it slid across the track.
Both riders were not injured as Marc Marquez clinched a sixth successive victory in 2014 by 0.121s on the final lap.
Crutchlow tweeted: "Really sorry to @stefanbradl for the bike being in track ! Was scary moments when in track with bikes coming at me. Improve in Barcelona …"
