London - Northampton's Wales wing George North will be out until at least the end of April after a series of head injuries, the English Premiership champions announced on Thursday.
North, 22, has three times taken heavy blows to the head while playing in the past two months and had already been ruled out of this weekend's European Champions Cup quarter-final away to French side Clermont.
Following consultation with head injury specialists, Northampton have decided to give the strapping wing further time to recover.
