Cape Town - AmaZulu have been dealt another telling blow this week, after it was established that defender Marc van Heerden would be sidelined from football for about two months.Van Heerden, who sustained a knee injury this month, did not feature during the Premiership fixture against Chippa United but the jury had always been out on how severe the situation was. The AmaZulu medical team has since learned that more time would be needed for recovery."Marc’s injury is unfortunately more serious than we thought and we estimate that he will be out for the rest of the year," said Usuthu’s biokineticist Burger van der Merwe on Wednesday."An MRI scan revealed that he has a grade 2 tear on his medial collateral ligament (MCL) and he also has a slight tear on his anterior cruciate ligament (ACL)."He has started his rehabilitation and he will be monitored regularly. With these kinds of injuries it’s better to take things slowly because we do not want to rush and risk losing him for a much longer period because he is important to the club," continued the statement.In what has been a bad injury week for the club, it has also been established that midfielder Larry Horaeb would need to undergo a late fitness test before determining if he can play when Usuthu travel to Free State Stars on Wednesday."With Larry it’s 50-50 at the moment because he is looking good but he’s also just come back from a fracture so we have to keep an eye on him," added Van der Merwe."He’ll probably undertake a late fitness test and we’ll take it from there."The good news for the Durban-based club is that Robyn Johannes, who returned from a mild knee injury on Saturday, and winger Nkosinathi Mthiyane, who came on as a substitute after recovering from a fractured arm, are expected to be available for selection.
