Trainers Aidan and Donnacha O'Brien have been fined €2,500 each and prohibited from attending race meetings in Ireland for two weeks for failing to enter the Curragh through the health screening area at a meeting last month.
The pair were found to have breached coronavirus health screening protocols at the County Kildare course on 12 June, which was Irish 2,000 Guineas day during the week racing resumed in Ireland.
The matter was heard by the referrals panel of the Irish Horseracing Regulatory Board on Monday.

IHRB press officer Niall Cronin said: "We noted the decision of the referrals committee and the various protocols regarding Covid-19 are very serious.
"It is important that they are strictly adhered to at all times to make sure that racing can continue in a safe manner for everyone involved."
With racecourse officials and the larger racing fraternity still coming to grips with the new restrictions, O'Brien Sr labelled the incident a "misunderstanding".
"It was my first day's racing since racing resumed and we went to go in the side gate we always use by the car park," the champion trainer told the Racing Post.
"We were allowed in and there were no questions asked. I went in and out a number of times during the day and nobody said anything to me. There was nothing untoward about it, it was just a misunderstanding, and we are fully supportive of all the measures in place to keep racing going."
