Two appeals concerning the finish of the Pretty Polly Stakes at the Curragh have both been dismissed by the Irish Horseracing Regulatory Board.

The Group One contest produced a messy conclusion as the George Boughey-trained winner Via Sistina drifted across the track in the final furlong, impeding the placed horses in winning by two lengths under Jamie Spencer.

Ben and Sir Martyn Arbib, who own Hughie Morrison’s second-placed Stay Alert, appealed against the raceday stewards’ decision not to revise the placings, but the IHRB dismissed that claim.

Spencer was given a six-day ban for his ride, with the jockey asking the IHRB appeals panel to reconsider the severity of the suspension.

However, that was also dismissed with Spencer ruled out on July 15, 17-20 and 22.

The suspension means he misses the ride aboard Khaadem in Saturday’s July Cup, with Rob Hornby booked to ride the 80-1 Queen Elizabeth II Jubilee Stakes winner at Newmarket instead.
