Cornish Pirates captain Chris Morgan is among four more players to commit to new deals at the Championship club.
The 34-year-old back-row has agreed terms for next season, as well as prop Paul Andrew, fellow forward Marlen Walker and centre Alex Dancer.
Morgan has not played since dislocating his shoulder in a 17-15 defeat by Jersey in September.
The Pirates last week agreed new deals for Matt Evans, Kyle Moyle, Rob Elloway and Tom Channon.
"It is great that we have signed these experienced Championship players," said director of rugby Ian Davies.
"Marlen, in particular, had interest from a number of Championship clubs, so to keep hold of him is testament to the environment we have here at the Pirates."
The club also has forwards Brett Beukeboom, Alex Cheesman, Marcus Garratt, and Tyler Gendall, plus backs Will Cargill, Alex Day, Laurence May, and Toby May under contract for next season.
