Springboks Arno Botha and Trevor Nyakane have been drafted into the Bulls match-day squad for Saturday's PRO14 Rainbow Cup SA clash against the Sharks in Pretoria.
Botha replaces Elrigh Louw at blindside flank in the only change to the starting XV from the one which beat the Stormers 20-16 in Cape Town.
A fit-again Nyakane will start off the bench in place of Jacques van Rooyen, while Louw will take Nizaam Carr's spot amongst the replacements.
Bulls director of rugby Jake White said he expected a thrilling top-of-the-table clash.
"We've had a few epic battles thus far and the Sharks will be keen to get one over us at Loftus as it is something they've yet to do," said White.
"The forward tussle is going to set the tone while both backlines are brimming with relentless talent so it should make for an exciting but hard encounter," he added.
Saturday's clash at Loftus Versfeld is scheduled for 18:15.
