London Welsh head coach Justin Burnell said his three latest signings were a signal of the club’s ambition.

Prop Cai Griffiths, lock Rob Andrew and scrum Ollie Frost were announced yesterday as Welsh prepare for their Greene King IPA Championship campaign at Oxford’s Kassam Stadium.

Griffths joins from London Irish, Andrew moves from Leicester and Frost has signed from Worcester.

Burnell said: “I am delighted with these three additional signings. I believe they reaffirm London Welsh’s ambitions for the forthcoming season.

“Cai’s experience with the Ospreys speaks for itself and Andrew and Ollie are two players that have come highly recommended.”
