Ulster have announce the signing of South African international lock Johann Muller on a two-year contract.
Muller will arrive in the province at the end of the 2010 Super 14 competition, and will join-up with the Ulster Squad on 1 July.
One of the leading lock forwards in South Africa, Muller (29) currently plays for the Natal Sharks and has represented the Springboks on 23 occasions, his final appearance being against the British and Irish Lions during last summer's Tour.
Standing at 6'7' and 114kg, the Mossel Bay born powerhouse made his provincial debut for the Sharks in 2003, going on to make his Super 14 debut against the Hurricanes later that season.
Muller was awarded his first Springbok cap against Scotland in 2006, captained South Africa against New Zealand in 2007 and also appeared in the 2007 Rugby World Cup in France.
Johann Muller has made over 130 appearances for the Sharks and captained the side during the 2008 and 2009 Super 14 competition. He also led the Sharks to Currie Cup victory in 2008.
