Trainer Luke Comer has failed in his bid to have a three-year suspension overturned by the Appeals Committee.

Comer's case was originally heard in 2023 following a long-running investigation by the Irish Horseracing Regulatory Board. It all began in October 2021 when the Comer-trained He Knows No Fear tested positive for anabolic steroids following a fourth-placed effort in the 14-runner Listed Trigo Stakes at Leopardstown.
