Concussion specialist Dr. Roger Zemek from the Children’s Hospital of Eastern Ontario has testified in the Rowan Stringer inquiry. Zemek says coaches do not have to be experts in concussions but they do have to possess some general knowledge about the sports injury. Many students suffer symptoms of concussion for up to a month after the injury, but don’t report to parents or coaches for fear of being pulled from the game. In the week leading up to her death, the Barrhaven rugby player told friends she had been suffering headaches and thought she might already have a concussion. Stringer went on to play in the game that lead to her death.
