Dublin - Springbok and Sharks scrumhalf Ruan Pienaar has signed a two-year deal with Irish outfit Ulster, beginning next season. Negotiations for his exact date of release are ongoing with the Sharks. Pienaar made his debut with the Sharks in 2005 before making his first appearance for South Africa in 2006 against New Zealand. He was also a member of the Rugby World Cup winning squad in 2007 and has won 36 Springbok caps. Pienaar will join two former Sharks colleagues, BJ Botha and Johann Muller, at Ravenhill.“Bringing Ruan to Ulster is a massive statement of our ambition to be competing with the top teams in the Magners League and Heineken Cup,” Ulster’s rugby operations director and former Ireland flyhalf David Humphreys said.
