Blue Bulls flanker Roelof Smit has been ruled out of Friday's Currie Cup clash with the Sharks in Durban due to injury.
Smit, who returned to action earlier this month after recovering from a hip pointer complaint, is sidelined with a wrist injury.
Meanwhile, the Bulls' utility forward Jacques du Plessis did not train on Monday due to a hip contusion, but will be back on Tuesday.
The Bulls have been boosted by the return from injury of Duncan Matthews (hamstring) as well as Justin Forwood (ribs). Ettienne Swanepoel (back) will be back in two weeks and Neetlingh Fouche (ankle) in one week.
Irne Herbst, Piet van Zyl, Callie Visagie, Morne Mellett, Nick de Jager and Dennis Visser will only play next year, team doctor Org Strauss confirmed.
