Vodacom Bulls centre Jan Serfontein has been ruled out for the remainder of their tour after suffering a knee injury.

Serfontein picked up a grade one medial knee ligament injury against the Chiefs last weekend and will fly home for further treatment and assessment. Jürger Visser has been called upon to replace Serfontein in the squad as he can also cover for Jesse Kriel, who is nursing a contusion on his knee.

Lappies Labuschagne is struggling with a bruised trachea that will prevent him from training until Thursday, a day before they face the Brumbies in Canberra.
