Nicky Henderson names top Flat jockey ‘quite possible’ to get Constitution Hill rideThe former Champion Hurdle winner is set to have his first start on the Flat at Southwell in February after a spate of falls over jumpsView 2 Images Constitution Hill: heading to Southwell to run on the Flat (Image: PA)Nicky Henderson has named the top jockey who it is 'quite possible' will ride Constitution Hill when he makes his Flat debut at the end of February. He is set to contest a mile and a half race at Southwell on February 20 following the creation of a 1m4f novices race worth £40,000 for horses aged four and above. He’s also going to do some schooling with Yogi Breisner next week so we’re definitely keeping him busy! “If that wasn’t to be the case we have Rob Hornby who rides out for us on occasions and rode at the Newbury gallops morning in November. He’s a very good jockey, although I don’t think we’ll be short of applicants!”
