Blue Bulls coach Frans Ludeke has a score to settle with his former team the Lions, who they entertain in an Absa Currie Cup game at Loftus tonight. Kickoff is at 7.10pm.
Ludeke was relieved of his coaching job at Ellis Park two years ago after a string of poor results in the prestigious southern hemisphere competition, the Super 14.
Now he has taken the Bulls to the top of the domestic competition with 23 points from six games. They are level on points with the second-place Cheetahs and the Sharks but both sides have played seven games.
The Pretoria side will be out to prove once more that they are best team in the "Home of Champions" after their emphatic 21-7 victory over their neighbours at Ellis Park in June.
l Western Province will be without leading points scorer Willem de Waal when they host the Sharks at Newlands tomorrow.
Flyhalf de Waal will be out of action for almost three months after suffering a hip injury and has been replaced by wing Joe Pietersen.
The Sharks will be reinforced by the return of Ruan Pienaar and Francois Steyn, who have been released by the Springboks.
l Bottom club Boland Kavaliers will host the Falcons in Wellington at 4pm tomorrow.
l Defending champions the Cheetahs take on the Wildeklawer Griquas from Kimberley in Bloemfontein at 6pm.
Meanwhile, about 350 youths joined the Springboks and Argentina's Pumas for a rugby clinic in Soweto, a rare occurrence in the township.
Black and white youths, including two girls, learnt how to pass the ball, tackle and scrum.
"Each child here should have a chance to play for the Springboks if they have got the talent. It hasn't always been like that," said injured Springbok captain John Smit.
Under apartheid , whites dominated rugby and still do to a large extent, but an increasing number of black youths have shown interest in the sport.
John Allan, chief executive of Rugby Legends South Africa, said "there is progress but it is not fast enough". - additional reporting by Sapa-AFP
