Ireland head coach Andy Farrell has branded the “circus” around son Owen Farrell’s disciplinary process “absolutely disgusting”.

The England captain’s participation in the World Cup is in fresh doubt after World Rugby appealed against the decision to overturn his red card from Saturday’s clash with Wales.

An independent disciplinary panel caused an outcry on Tuesday when it cleared 31-year-old Farrell to play following his shoulder-led tackle to the head of Taine Basham, which was expected to result in a significant ban.

England head coach Steve Borthwick has subsequently opted to leave the Saracens fly-half out of his squad for Saturday’s World Cup warm-up clash against Ireland in Dublin.

Farrell senior, who concedes his view on the situation is not impartial,  expressed anger at some of the intense criticism his son has faced.

“Whatever I say is probably flawed anyway,” said the 48-year-old.

“When you’re talking about somebody’s son and asking the question, it’s always going to be flawed, so what does that really matter?

“I don’t normally say too much because of that type of reason about my son.

“But what I probably would say at this moment in time is that the circus that’s gone on in and around all of this is absolutely disgusting, in my opinion, disgusting.

“I suppose those people that have loved their time in the sun get a few more days to keep going at that.”
