Sjef Janssen Suffers from Torn Muscle Fiber

Belgian national dressage coach Sjef Janssen has injured himself severely to his hamstring. Last week, so reported, the husband of Anky van Grunsven tore his hamstring due to a sudden wrong movement. An MRI confirmed the diagnosis. Next week, the Medical Center in Amsterdam will tell Janssen whether surgery is required or just rehabilitation. The recovery will take a very long time and a full recovery is not to be expected.
