Belgian national dressage coach Sjef Janssen has injured himself severely to his hamstring. Last week, so eurodressage.com 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.
