Despite three first half tries, the Scarlets lost 24 points to 23 against Edinburgh in the Pro 12.
The Scarlets have been fined €10,000 (£7700) by the body in charge of European rugby for fielding an ineligible player on their bench during January’s European Champions Cup fixture with Racing 92 in Stade Yves-du-Manoir.
Wing Jacob Cowley featured on the bench for the West Wales outfit but did not come on the field of play during the 64-14 defeat but governing body EPCR nevertheless found the Scarlets guilty of misconduct at a hearing of the independent Disciplinary Committee.
The committee did however accept that the breach was made in error but did still constitute a breach of tournament rules.
The fine has been suspended but will become payable if the Scarlets are found to breach any further tournament rules between 18th Feb 2016 and 31st May 2016.

He went on to make 16 appearances in his first season with the region. He made his 100th regional appearance in Friday evening’s victory over Edinburgh Rugby.
His Wales debut came in June 2012, against the Barbarians, at the Millennium Stadium.
