He came on as a first-half replacement and scored a try just after half-time in a 31–24 victory.^[6] He was also included in the squad that embarked on a two-match tour of Argentina.^[7] He came on as a replacement in their 25–22 victory over Argentina^[8] and started their second tour match a few days later, in which he scored two first-half tries in a 39–28 victory.^[9]
