Jockey Tom Halliday died from injuries sustained in a heavy fall at Market Rasen on Sunday 3 July 2005.
His death was the first on a British or Irish racecourse since Sean Cleary died from injuries sustained in a fall at Galway in October 2003.
Halliday, 20, was aboard Bingley trainer Sue Smith's Rush'N'Run when the six-year-old fell three out in the Bet With Don Novices' Handicap Hurdle.
He was taken to Lincoln County Hospital where he died from his injuries.
Halliday's fledgling career had seen him win three hurdle races - the first of which came at Wetherby in December 2004 - and one National Hunt Flat race.
Jockey Club public relations manager Paul Struthers said: "We are shocked and saddened to hear the news and the Jockey Club's condolences go out to Tom's family.
"We will be holding a full review into the incident and will be offering our full assistance wherever necessary."
British Horseracing Board chief executive Greg Nichols said: "This is shocking, terrible news. The thoughts of BHB and all the sport are with Tom's family."
Champion jockey Tony McCoy said: "Words just can't say how it feels. He was only 20 with his career in front of him.
"Even if you don't know someone well, it still hits you hard when something like this happens as they are there in the weighing room with you every day.
"All the lads are devastated. The weighing room is usually a happy place but something like this makes it so you just don't want to be there."
All four race meetings taking place on the following Monday held a minute's silence before racing to honour Tom.
