World rugby to contact RFU over handling of George North's head injury

World Rugby will seek further information from the Rugby Football Union about an "apparent non-compliance" with its protocols over the handling of George North's recent head injury.

A joint RFU and Premiership Rugby investigation opted against charging Northampton or their medical staff with misconduct for allowing North to resume playing, despite the Saints winger appearing to have been knocked unconscious in a league match on December 3.
