The NSW Waratahs have signed Dean Mumm and Leon Power for the 2017 season.

Mumm, who has represted the Wallabies on 48 occasions, has re-signed for the Waratahs, after returning to the club last year after spending three years at the Exeter Lions.

Power returns to Super Rugby after two years with European Top 14 club, Oyonnax.

He played 20 games for the Brumbies from 2012 to 2014.

“Both Leon and Dean are quality players with a wealth of knowledge,” coach Daryl Gibson said.

“The lineout is a key growth area for us next season. We need to be able to win quality ball and these two players have the ability to analyse and lead that.

“Their experience will provide a good balance with the new talent coming through the team.

“They will help to develop and nurture the next generation of NSW locks in Ned Hanigan, Senio Toleafoa, Ryan McCauley and Will Skelton.”
