Trainer Sean Curran said he was "shocked and flabbergasted" after his heavily gambled runner was prevented from running at the last minute on Tuesday.
Aces Full, who was backed from 14/1 into 9/4, was due to run in a novice handicap chase at Exeter, but the stewards at the course ordered the eight-year-old to be withdrawn after a request from the BHA’s integrity department to interview connections.
The horse, who had been off the track since last October, was due to have his second run for the trainer, with his best racecourse run to date seeing him finish sixth of nine runners in a beginners chase at Naas in March 2021, when he was beaten by over 35 lengths.
