Wests Tigers coach Tim Sheens has called into question the inconsistencies in rugby league's concussion laws, after Robbie Farah was ruled out of the round-18 NRL clash with Canterbury following a heavy head knock suffered in the State of Origin decider.
NSW hooker Farah suffered the knock in the opening exchanges of Origin III and was allowed to play on despite appearing to be heavily concussed.
With no backup on the bench, the Blues were desperate for Farah to play on, but Sheens suggested that if Farah had copped the knock in a club game, the Tigers' rake would not have been allowed to continue.
"The fact we would not be able to do that at club level is an issue," Sheens said.
"That will be something to be discussed later on - what we are allowed to do at club level and what you are allowed to do at rep level.
"Obviously, there are different rulings as to what you can do at club and rep level. But I don't think there should be any extra leeway given there to rep players or rep doctors."
Farah has been affected by concussion already this season, and Sheens said it was a concern, but stressed the Tigers had followed NRL protocols each time Farah had returned to play.
The Tigers meet high-flying Canterbury on Friday night at Allianz Stadium and star pivot Benji Marshall said the loss of Farah was a blow to the Tigers' hopes but he was confident they had the players to overcome it.
"It makes it a bit tougher," Marshall said.
"But we have been training all week without him. It does take away a bit from our firepower but we have a couple of guys who have been standing up each time he has been out. We know it will be a tough game but we just have to turn up."
Sheens said Masada Iosefa or Tom Humble would take Farah's spot in the Tigers' starting side, with the other likely to play off the bench.
After stringing together seven successive wins mid-season, the Tigers have suffered back-to-back upset losses to the struggling Sydney Roosters and Newcastle.
Sheens said fans could expect a more-disciplined effort from the Tigers against a Bulldogs side who sit second on the ladder on the back of five straight victories.
"We need to go out and knuckle down and rediscover some of that form from that seven-week period," Sheens said.
"We need to have better ball control and our penalty count hasn't been good the last two weeks and we have paid the price."
Sheens said Gareth Ellis and Tim Moltzen were still a week away from returning from injury.
