London Welsh can confirm eight new signings as the club prepares for the run in to the Greene King IPA Championship season.

Joining the Exiles are USA Eagles flanker John Quill, Munster prop Paddy Ryan and versatile former London Wasps Academy back Liam O’Neill, while there’s a return to the club for scrum half Tyson Keats.

Arriving on dual registrations are Worcester Warriors and England U19 wing Josh Watkins and Bath second row Will Spencer.

London Welsh head coach Justin Burnell said: “The potential within this group of players is remarkable. There’s pace, skill, size and experience.

“What these signings demonstrate to me once again is that London Welsh will leave no stone unturned to further strengthen its squad in the pursuit of success.”
