Harlequins confirmed that second-year Academy Member Archie White has re-signed with the club, while Gloucester Academy prop, Josh McNulty, will join the Club from the 2017/18 season.
Harlequins Director of Rugby, John Kingston confirmed the news and said: “We have been looking out for a young tighthead prop who we believe can be moulded into a quality Premiership player one day and we feel that Josh possesses the attributes for that to happen.
“Under the outstanding coaching skills of Graham Rowntree and Adam Jones, I am sure Josh will make the necessary strides.
“I am also delighted to have extended Archie White's contract by a further year.
“He is a talented back row forward who has had a tough time with injuries this season. I hope he will be able to follow in the footsteps of many outstanding back row forwards that this Club has developed over recent years."
Tighthead prop McNulty, formerly of Coventry and Worcester Warriors, will join from Gloucester Rugby. The 23-year-old has made four senior appearances for Gloucester across the European Challenge Cup and the Anglo-Welsh Cup since his debut in December 2015.
