Worcester Warriors hooker Ollie Hayes has re-signed for Bristol after two seasons away from the Memorial Stadium.
The former England Under-18 international made 37 appearances in his first spell at Championship club.
"I'm delighted to be back at Bristol - it's a club that is close to my heart," the 23-year-old said.
Hayes, who played 10 games during his spell at Sixways, is the third Warriors player to switch to the West Country outfit ahead of next season.
"Ollie is a consistent performer who knows Bristol and the values that the club holds," said director of rugby Andy Robinson.
"He's got top flight experience and, as a young player, there is still plenty of time for him to develop."
