George North has undergone a setback as he seeks to battle back from the injury that has sidelined him for close on 12 months.
The 102-cap Wales international damaged anterior cruciate ligaments in his right knee while playing for the Ospreys against Cardiff last April. His region had hoped he would have been able to return for their United Rugby Championship clash with Zebre on March 6.
But his comeback has been delayed, with North currently at home rather than in South Africa, where the Ospreys are playing the Lions and Stormers during a short tour.
