Jatinder Rakhra finished in third place in the 60kg event in Poland
GB wrestling manager Shaun Morley said he was delighted with progress after the team won five medals in Europe.
Britain ranked fifth from 18 countries in Sardinia after Krasimir Krastanov, Myroslav Dykun and Leon Rattigan all took third-place finishes.
At the Krasnik International Tournament in Poland, Jatinder Rakhra and Craig McKenna also won bronze medals.
"Our young wrestlers are becoming very competitive at an international level," said Morley.
"As we look ahead to the London 2012 Olympics, I am delighted at the progress we are making."
