Bristol have secured the signing of versatile forward Jon Fisher from Northampton Saints.
The 27 year-old, who can play across the back row, made 25 appearances in two seasons at Franklins Gardens.
The newly-promoted club also announced the arrival of USA Sevens star Thretton Palamo from Saracens.
He said: “I’m pleased to be joining Bristol at such an exciting time for the Club with a new stadium and Premiership rugby to look forward to.
“Last season’s play-offs underlined the passion and size of the fanbase here and I’m relishing the challenge of performing at Ashton Gate.”
Director of Rugby Andy Robinson added: “Jon is an experienced Premiership performer and has the right characteristics to fit in well in our environment.
“He’s a young man whose versatility provides us with plenty of options. Jon is highly regarded by those who have coached him and we’re looking forward to welcoming him to Bristol.”
