Cardiff Blues' director of rugby Phil Davies has admitted that he was 'unhappy' with the decision to hand Lloyd Williams a red card in Sunday's 35-24 Heineken Cup defeat to Montpellier.
Williams was handed his marching orders after just 25 minutes of the action, but Davies has claimed that the decision was "unfortunate".
"It was a bit of a rustic challenge, I think we will contest it but we will have to have a look at it. But I am not sure it was the right decision," Davies told Sky Sports News.
"It was unfortunate, in the last few weeks Lloyd has been playing really well but aside from that I thought the way we adjusted to the setback was really pleasing.
"A couple of loose kicks cost us and we did not go through the phases down in their half often enough to get extra penalties or even potentially score a try, but overall the effort and determination was fantastic."
Cardiff were leading 9-6 at the time of the dismissal.
