The Blue Bulls' win over the Golden Lions in Pretoria came at a cost when it was revealed that their captain Arno Botha suffered an injury in the match.
Blue Bulls team doctor Herman Rossouw confirmed that the Springbok back-row dislocated his shoulder.
"He went for a scan this morning but is unlikely to train again this week and play on the weekend," said Rossouw on Monday.
Botha's injury wasn't the only concern ahead of this weekend's clash against the Pumas in Nelspruit.
"Duncan Matthews, sustained a knee injury," added Rossouw.
"He will be out for at least four weeks."
