Worcester Warriors hooker Joe Taufete'e and centre Wynand Olivier have both signed new contracts with the Premiership club.
USA international Taufete'e, 25, who joined from San Diego Breakers in 2016, has signed a two-deal deal.
Experienced South Africa international Olivier, 34, has agreed a one-year extension at Sixways.
Luke Baldwin, Ryan Mills, Sam Lewis, Niall Annett and Dean Hammond have all recently signed new Warriors contracts.
"My journey in rugby has been a special one and I hope I can continue that upward spiral with Warriors in the future," said Taufete'e.
Olivier, who helped South Africa win the 2007 Rugby World Cup, has scored 13 tries in 45 appearances for Worcester since joining the club in 2015.
"Wynand is a consummate professional. Having someone of his experience in the squad is vital," said Warriors director of rugby Alan Solomons.
Worcester, who are 11th in the Premiership, have appointed Rory Duncan as their next head coach, to replaced Carl Hogg, who is to leave at the end of the season.
