Nick asks members of the public not to share photos or videos of the incident on social media
The father of sidecar competitors Ryan and Callum Crowe say the brothers have fractures and a head injury but there is no risk to their lives.
The update was made by Nick Crowe on Facebook late last night.
During TT qualifying, the duo came off on the first lap in Crosby resulting in a red flag.
In another post, Nick is asking that people not share videos or photos of the incident on social media.
He says they don't want to damage the event, which is hugely under scrutiny, adding they'd like to keep the sidecar class going.
