The Canberra Raiders Cup has become one of the first local leagues in NSW to implement an 18th man policy to help clubs deal with failed head injury assessments. Similar to the recent changes implemented by the NRL, local clubs name an 18th man in their match day squad who can be activated should a player fail an HIA. But unlike the NRL, whi,ch requires three HIA failures before an 18th man is activated, Canberra Raiders Cup sides can use their fifth bench member after just one player cops a head knock and is unable to pass the assessment. League general manager Mark Vergano said the rule would help trainers as well, allowing them to err on the side of caution, with a team no longer disadvantaged by losing a player to a failed HIA test. "We have a duty of care to the players and as a sport we are probably one of the best prepared to handle concussion, with all of our trainers level one or two qualified," Vergano said.
