Trainer Luke Comer has lodged an appeal against "various elements" of last week's decision by the Referrals Committee to find him guilty of damaging the good name of Irish racing by failing to prevent 12 horses in his Co Dublin yard being administered anabolic steroids.

Comer was given a three-year training ban, fined over €80,000 and ordered to pay €755,000 towards legal costs incurred by the Irish Horseracing Regulatory Board [IHRB].
