Jason Maguire forced to retire on medical grounds
GRAND National-winning rider Jason Maguire has called time on his career in the saddle after having his comeback from a back injury stalled for over a year.
Maguire, 36, has been sidelined since suffering slipped discs in a fall at Musselburgh in February 2015 and has made the decision on medical grounds.
Speaking to the Racing Post, his agent Chris Broad said: "Jason informed me this morning that he will not be returning to race-riding for medical reasons. He is therefore retiring as he will not pass the medical for his licence to be renewed."
Having undergone surgery two months after his Musselburgh fall, Maguire had hoped for a quick return and has been riding out regularly since July last year. However, he suffered with a troublesome sciatic nerve and failed to get the all-clear from the BHA medical team.
Less than a year earlier, he was placed in an induced coma after receiving life-threatening injuries in a fall at Stratford on the eve of the Cheltenham Festival. He suffered a fractured sternum and required an operation to have parts of his liver removed.
The pinnacle of Maguire’s career came when steering Ballabriggs to victory in the 2011 Grand National for Donald McCain, while he also enjoyed fruitful partnerships with stablemates Peddlers Cross, Overturn and Cinders And Ashes.
He rode over 1,000 jumps winners in Britain, including five at Grade 1 level, and finished runner-up to Sir Anthony McCoy in the jump jockeys' championship in 2012-13 when he equalled his best haul of 144 from the previous season.
While on the sidelines Maguire has been working as racing manager to owners Paul and Clare Rooney.
