Newcastle’s Argentina second row Pedro Rubiolo will join Premiership rivals Bristol next summer.
The 21-year-old, who has won 19 caps for the Pumas, has signed what Bristol describe as a “long-term deal” at Ashton Gate.
Rubiolo has played 21 times for Newcastle since joining the club in January 2023.
He was part of the Argentina side that reached the semi-finals at the last Rugby World Cup.
He helped Argentina beat New Zealand and South Africa in this year’s Rugby Championship and has started all three of his country’s matches this autumn.
“Pedro is one of the rising stars of Argentinian rugby and is already established himself as the starting lock in the Pumas squad at just 21 years old,” Bristol Bears director of rugby Pat Lam said.
“He has impressed both domestically with Newcastle Falcons and internationally with the Pumas.
“We’re excited by the physicality and work rate that he will add to our forward pack, and we look forward to welcoming Pedro into the Bears family next season.”
