Stig Broeckx (Lotto-Soudal) is reported to be in a coma after an incident involving a motorbike at the Belgium Tour.

The third stage of the race was initially neutralised but was then cancelled when the seriousness of the crash became clear.

It’s thought that a moving moto collided with a stationary moto, and both then collided with a group of riders.

Broeckx had only recently returned from a broken collarbone suffered in a collision with a motorbike at Kuurne-Brussels-Kuurne.

Tony Martin (Etixx-Quick Step), who was in the race but not involved in the crash, tweeted about the incident not long after the race cancellation:

The UCI press office tweeted a short statement later in the afternoon:

Other twitter users posted photos of the immediate aftermath:

This is a new incident in a growing list of collisions involving race vehicles, the regularity of which seem to has increased over the past few seasons.

Earlier this year Antoine Demoitié died after a motorcycle landed on him following a crash. His team, however, refused to blame the moto driver for their rider’s death.
