From a farming family in Norfolk, Jack van Poortvliet attended Tigers Rugby Camps at North Walsham RFC before joining the club’s developing player programme and then entering the academy system.
Originally a fly-half, Jack moved to scrum-half and played in back-to-back Under-18 League title-winning squads with Tigers in 2017/18 and 2018/19.
The 2018/19 campaign also featured a first experience of senior rugby in the Premiership Shield and appearances for England Under-18s for the Oakham School student.
He made his senior debut for the club at the start of 2019/20 and a first Premiership start at Sale Sharks before his 19th birthday among five first-team appearances in that campaign.
