Bristol have signed South African back-rower Nick Koster on a season-long loan from Bath.
The 24-year-old, who can cover both flanker and number 8, arrived at The Rec from Super Rugby's Western Province in October.
He made three appearances from the bench in the Premiership last season.
"Nick gives us another option in a competitive back row," said director of rugby Andy Robinson. "His versatility will be a benefit to us."
Koster added: "Bristol is a great club who clearly have ambitions to be in the top flight.
"There are some excellent players in the squad already, so I'm relishing the opportunity to work hard to force my way into the starting line-up.
"I'm still learning as a player and experiencing a league as combative as the Championship will only be good for my development."
