Pretoria - The Bulls have kept their run-on side unchanged for their Super Rugby match against the Brumbies at Loftus Versfeld on Saturday.
Coach Frans Ludeke, however, is still sweating over the availability of prop Dean Greyling.
Greyling will be assessed by the Bulls medical team later in the week.
If the prop does not recover from a bruised shoulder in time, Ludeke will hand Dawie Steyn a Super Rugby debut.
Gerrit-Jan van Velze will replace flank Dewald Potgieter on the bench.
