He got hit on the head in a game and had a bit of delayed concussion. His symptons have kept resurfacing when hes been putting the effort into training so, under medical advice, weve had to step him back and take our time with him. At the moment hes in some kind of sabbatical. Hes sat at home waiting for his symptons to calm down. Were monitoring him almost daily. When hes ready to go, hell have to go through six or seven days of training before hes allowed to be up for selection. Thats in the medical peoples hands.
