The 31-year old joins from Edinburgh Rugby on a two-year deal having made 130 appearances for the club.

He has won 28 caps for Scotland and appeared throughout the 2014 RBS Six Nations.

Irish director of rugby Brian Smith said: “It is great to have a player of Geoff’s talent and experience joining our squad next season. He is a genuine International tighthead who has performed exceptionally well in the recent Six Nations Championship.

"We will have plenty of competition in the front row next season that will only benefit the squad.”

Commenting on his decision to sign for the Exiles, Scotland international Cross, who is also a qualified doctor, said: “Moving down to London Irish is a fantastic opportunity for me. Having met with Brian, discussed the vision of the club and seen the new training facility it was clear to see the intent the club has moving forward.

“Leaving Edinburgh was a difficult decision and I will leave with many fond memories, however I am excited to be moving to Sunbury and look forward to the challenge ahead.”
