This RTE documentary takes a look at  the ever-growing and troubling issue of concussion in rugby. Featuring interviews with Ronan O'Gara, Jonny Sexton, as well as the first Irish professional rugby player forced to retire because of concussion, John Fogarty. The documentary asks if enough is being done to protect players both on a school and international level, and, if you'll excuse the pun, is sure to be hard-hitting and a must watch.
