Downpatrick racecourse will donate all proceeds from Friday's meeting to the Jonjo Bright Trust Fund with an auction of top sporting items, featuring a Manchester United shirt signed by Wayne Rooney, also being held.
The local track has previously donated use of the corporate hospitality suite to the Trust Fund to stage an event for young Ulster jockey Jonjo Bright who sustained life changing injuries earlier this year in a fall while racing.
Many high-profile items will be auctioned including Rooney's shirt which has been donated by Sir Alex Ferguson.
For golf fans, there is a shirt signed by Ulster's former Open champion Darren Clarke and a four-ball plus lunch at Royal County Down.
Racing lots include a saddle signed by the great Tony McCoy, a set of signed JP McManus racing silks, a print of Camelot signed by Aidan and Joseph O'Brien, a pair of breeches signed by champion flat jockey Richard Hughes, a tour of Coolmore Stud plus lunch, a morning with trainer Gordon Elliott with lunch for two at Fairyhouse racecourse and a morning with trainer Noel Meade and lunch at Navan racecourse.
Other items include a framed set of breeches and whip signed by 18-times champion jockey McCoy, an Istabraq print signed by JP McManus, trainer Aidan O'Brien and jockey Charlie Swan and Sprinter Sacre's number cloth from the Boylesport Champion Chase signed by Barry Geraghty and Nicky Henderson.
Advance telephone bids can be made on 028 44 612054 or by e-mail to email@example.com
There will also be a ballot on the day with prizes including admission and lunch at Punchestown for four on John Durkan Chase day, admission and lunch for two on Irish Champion Hurdle Day at Leopardstown plus two tickets to see Manchester United against Arsenal at Old Trafford.
