Tony Smith has urged the decision makers to introduce an 18th man after three Hull KR players suffered head injuries in the win over Salford Red Devils.
George Lawler and Dean Hadley failed HIAs in the first half, while Jordan Abdull was left dazed by a late hit that resulted in a red card for Pauli Pauli in the dying seconds.
Rovers had two interchanges for the second half and were relieved to come through the second half unscathed until the very last play of the game.
Smith spoke out on the issue in the aftermath of the match against Huddersfield Giants in April and repeated his call for Super League to follow the NRL’s lead by introducing a concussion substitute.
“It does raise that question once again over the 18th man,” said the KR head coach.
“The NRL have changed it so they have a player who can come in if you lose somebody for the game.
“We lost three with head injuries so it’s probably worth mentioning in our media as well that we need to take care of our players.”
Rovers will monitor Lawler, Hadley and Abdull leading into the game against Wigan Warriors next Friday but will take no risks as they enter a gruelling period.
After travelling to Wigan, KR face St Helens before taking on Hull FC and Catalans Dragons in the space of four days, followed by a date with Warrington Wolves.
It will get even tougher after the break for the Challenge Cup final, with the Robins facing two four-day turnarounds as they play 11 fixtures in eight weeks to round off the campaign.
Smith spoke with apprehension as he considered the strain the players will be under during those periods.
“I’m scared because of some of those head injury reasons and having to play people under duress and fatigue,” he added.
“We’ve got to embrace it and get on with it. We’ll focus on making sure people don’t play under too much duress if we can help it where we can.
“Hopefully we’ve got enough players fit and healthy by then.”
