Young and promising Brisbane defender Justin Clarke has announced his retirement due to a concussion he suffered during a training drill in January. He has been sidelined since the injury. In a media statement, Clarke said he had consulted several specialists who told him he could no longer play contact sports. Any sort of head knock, no matter how minor, could cause symptoms to recur, lengthen recovery time, and possibly cause permanent damage. He has had memory issues and has not been able to exercise in any way since the injury. However, the specialists did tell him this all will pass and he will recover in time.
