Sale Sharks have re-signed hooker Neil Briggs from Leicester Tigers and agreed a new deal with second-row Jonathan Mills, both on two-year contracts.
Briggs, 29, spent six years at the Sharks before leaving to join French side Bourgoin in 2011.
Ex-London Welsh captain Mills, 30, joined Sale in 2013 after the Exiles' relegation from the Premiership.
"Jonathan played a big part in our success last season and has been a key player," said Sale boss Steve Diamond.
"As for Neil, he needs no introduction to Sale fans.
"After leaving us he has picked up a wealth of experience and I believe that he has got better and better as his career has developed."
