Hurricanes back-row star will honour his agreement and is due to arrive in Gloucestershire later this week to begin pre-season training.
Manu Samoa flanker Jack Lam is set to join up with his Bristol team-mates this week as they plot a route to the Aviva Premiership.
The 26-year-old agreed to join the south-west club earlier in the year but doubts were cast on his arrival after Bristol failed to achieve promotion to the English top-flight.
London Welsh pipped them in a two-legged play-off and the Memorial Ground outfit will now have to start again and put together a title-winning season in the second tier.
Reports claim that the Hurricanes back-row star will honour his agreement and is due to arrive in Gloucestershire later this week to begin pre-season training.
Lam is one of a number of new faces at Bristol, with former Wales scrum-half Dwayne Peel moving to the club from Sale and handed the captain’s armband, while British & Irish Lions lock Ian Evans, fly-half Matthew Morgan, David Lemi and Anthony Perenise have all come on board during the summer months.
