England captain Owen Farrell's involvement in the upcoming Rugby World Cup was thrown into doubt on Thursday when World Rugby announced it would appeal the decision to overturn his red card from a recent match against Wales.
Farrell was sent off during England's 19-17 win at Twickenham last weekend after the "bunker" review system upgraded an initial yellow card to red after he made contact with Taine Basham's head during a should-led tackle.
The flyhalf, who has been suspended for dangerous tackling in the past, was facing a six-week ban that might have ruled him out of the start of next month's World Cup in France.
