Hundreds of tributes are being made on motorcycle forums to mourn the loss of T.T. star Martin Finnegan.
The 29 year old from Lusk in County Dublin died in an accident during the Supersport Race at Saturday's Tandragee 100 meeting.
Three spectators suffered non-life threatening injuries in the incident.
Finnegan had earlier won the opening race, the 43rd Irish road victory of his career.
T.T. and Motorsport Development Manager Paul Phillips is at the British Superbike round at Oulton Park this weekend, where a number of T.T. riders are competing.
Paul says they will all find it very difficult:-
