Siale Piutau: Former Wasps centre signs for Bristol Rugby
Bristol have signed Tonga captain Siale Piutau from Japanese club Yamaha Jubilo in a deal starting from January and running until the end of the season.
Centre Piutau made 12 Premiership appearances for Wasps last season, having joined them on loan in February.
The 31-year-old previously played for Chiefs and Highlanders in Super Rugby before moving to Japan in 2012.
"He will give the squad a boost in a crucial period of the campaign," interim head coach Mark Tainton said.
"I know Siale from his time at Wasps and he's a big presence in the midfield who carries hard and is a reliable defender."
