Cardiff complete Nick Williams capture

Ulster number eight Nick Williams will join Cardiff Blues on a long-term contract before the start of the 2016-17 season.

Williams, 32, has scored 13 tries in 67 appearances during four years with Ulster.

The New Zealander has also played for Auckland Blues, Munster and Aironi.

"I'm excited about what Cardiff Blues are looking to achieve, both on and off the field in the coming years," Williams said.

Cardiff Blues head coach Danny Wilson said Williams has been one of the "standout performers" in the Pro12 during the last few seasons.

"I spoke to Danny at length about the region and his plans," added Williams. "I'm now looking forward to using my experience to help the team and getting stuck in.

"I've enjoyed my time in Belfast and it's been a successful time at Ulster - I'll be giving everything until the end of this season for the team."
