Retired Springboks lock Victor Matfield will join the Bulls coaching staff for next year's Super Rugby competition.
The Bulls said on Monday the 110-times capped Matfield will work with his former provincial team as a specialist coach, concentrating on lineouts and forward play.
Matfield, South Africa's most capped second rower and second-most capped player, will begin a career as a television pundit in 2012 but was given permission to also work for the Bulls as a consultant.
Matfield said he was eager to start his TV job, "but it is no secret that I want to become involved in coaching too. This will afford me the opportunity to do both, something that I am very pleased about."
Matfield, 34, won the World Cup with the Springboks in 2007 and Super Rugby titles with the Bulls in 2007, 2009 and 2010.
He retired after South Africa's quarterfinal exit at this year's World Cup in New Zealand, ending a 13-year provincial career and 10 years with the Springboks. He was considered one of the best lineout forwards to play the game.
"This is great news for us," said Bulls head of rugby and Matfield's former coach, Heyneke Meyer.
"Vic has been the backbone of the Bulls for many seasons and to have his continued presence in the team, although unfortunately not as a player anymore, is a real bonus for us. We are proud and honoured to have him around."
