One of Ireland's most accomplished point-to-point jockeys was mourned on Friday following his sudden death at work, aged 44. Mikey O'Connor had secured more than 429 point-to-point victories since his maiden triumph 26 years ago, placing him fifth in Ireland's all-time rankings.

He also claimed 90 winners under rules, with his greatest achievement coming in a Listed race for Mick Winters in 2009. He was the inaugural rider to triumph on Winter's future Grade 1 victor Rebel Fitz and had also contributed to the career of Cheltenham Festival champion Forpadydeplasterer, securing victory on his bumper debut.

O'Connor had also tasted success as a trainer, preparing 27 point-to-point victors and 21 under rules.

According to the Irish Field, O'Connor died of a suspected heart attack at his Co Cork stables.

Horse Racing Ireland said: "We are deeply saddened to hear that Mikey O'Connor has passed away. We send our condolences to his family, friends and racing colleagues.

"Mikey was one of Ireland's leading point-to-point riders riding over 400 winners and won three Southern titles. May he rest in peace."

Father-of-three O'Connor had to overcome significant injuries during his career, the most serious which occurred after a last fence fall at Boulta in 2014.

O'Connor had to be airlifted the hospital and while he continued to ride with success, he required medical clearance from the raceday doctor each time he was in action. His teenage son Dylan, a former pony racing champion, has already ridden four winners in his debut season as a Flat apprentice.

O'Connor was instrumental in the early career of the legendary Denman, the 2008 Cheltenham Gold Cup winner, having ridden him during his initial training and schooling when he was known as 'The Tank'.
