England captain Owen Farrell is free to face Ireland on Saturday after his red card against Wales was not upheld by a disciplinary hearing.Farrell was sent off in a 19-17 World Cup warm-up win at Twickenham on Saturday when his yellow card for a dangerous tackle on Taine Basham was upgraded to a red by the 'Bunker' review system.But the hearing decided that a "late change in dynamics" due to Jamie George’s involvement in the contact area "brought about a sudden and significant change in direction from the ball carrier".Using this mitigation, it was decided by the all-Australian panel that Farrell – who was expected to face a mid-range sanction of a six-week suspension – should have been sanctioned with a sin-binning only.England had feared he would miss the pivotal opening World Cup group clash with Argentina in Marseille on 9 September but Farrell could now line out against his father Andy's Ireland side at the Aviva Stadium this weekend.
