Leicester have signed international props Michele Rizzo and Aniseko Sio.
Rizzo, 31, will join his fellow Italy Test forwards Robert Barbieri and Leonardo Ghiraldini in making the move from Treviso.
Sio, 21, heads to Welford Road after making his Test debut for Samoa against Japan last month.
"Michele Rizzo is an experienced player in Europe and at Test level, while Aniseko Sio is a young player who wants to come and develop his game with us," Leicester rugby director Richard Cockerill said.
"We have a very good group of senior props led by Marcos Ayerza, Dan Cole and Logovi'i Mulipola, plus younger guys Fraser Balmain and Tom Bristow who have some first team rugby experience with us, and Tiziano Pasquali and Riccardo Brugnara who have been coming through.
"We look forward to seeing Michele and Aniseko working with them in the new season."
