Bristol have released centre Mark Denney and scrum-half Jacob Rauluni.
Denney, 31, is retiring from professional rugby while Rauluni, who only signed for the club last summer and started nine games, has returned to Fiji.
Bristol chief executive David White explained: "Mark has decided he would like to pursue his professional interests outside rugby, a decision that is fully supported by Bristol Rugby.
"Jake, having played for the Barbarians in May, has returned home to consider his future options."
