Bristol flanker Marco Mama has signed a one-year contract extension.
The 22-year-old former Zimbabwe Under-20 international came through the West Country club's academy set-up and made his debut in 2009.
He has now made 60 first-team appearances for the Championship outfit, scoring six tries.
"A lot has changed since I made my debut in 2009 and it's clear that the club are moving forward," Mama told the club website.
Director of rugby Andy Robinson added: "It's vital that Bristol continue to nurture young talent and Marco is an example of how successful the academy system can be.
"He has a fantastic energy for the game and his displays have impressed me.
"Marco continues to mature as a rugby player and his versatility provides us with a number of options across the back row."
