South Africa second row Victor Matfield has been cleared to face the Waratahs on Saturday after being cleared of two counts of foul play.
The Bulls ace was asked to appear before a SANZAR judicial committee on Monday after he was cited for striking and charging into a ruck during the 50-32 victory over the Brumbies.
However Matfield was found not guilty on both counts at the hearing at Loftus Versfeld.
Pierre Spies and Danie Rossouw are also expected to line-up against the Waratahs after the duo were declared fit.
Spies suffered a knee injury in the win over the Brumbies but the problems is not as bad as first feared.
Team doctor Org Strauss said: "He actually injured a muscle behind the knee, which was good news, at we feared for some structural damage to the knee. We expect him to be fit.
"Danie Rossouw also trained with the team today. He will be on light duty during the week, but is expected to play."
The Bulls should have Dewald Potgieter also available, but centre Jaco Pretorius is definitely out.
