Oh, no, please, not another case of concussion!
Hurricanes first five Beauden Barrett's late withdrawal due to headaches, saw Otere Black wear the No.10 jersey and the latter added three conversions and a penalty to keep the Bulls at bay.
Boyd said the source of Barrett's head aches was still unclear, but he had been withdrawn from the match by the medical team as a precaution.
Barrett left the field at halftime during last weekend's win over the Cheetahs in Wellington, passed a concussion test and had shown no symptoms until the team landed in Johannesburg.
Although the team doctor was unsure whether his headaches were due to travel, altitude or humidity, it was decided the day before the match to withdraw him from the Bulls match the day before kick off as a precaution.
Barrett had exercised earlier in the week without any issues, Boyd said.
