Farah suffered a head injury in the opening exchanges of Wednesday’s Origin decider in Brisbane but remained on the field despite appearing concussed.
Tigers coach Tim Sheens questioned the decision to allow Farah to play on.
“There are obviously different rulings in every area of rep football versus club level. In this area, I don’t think there should be,’’ Sheens told the Tigers’ official website.
“I’m not concerned about him finishing the game but the fact we wouldn’t be allowed to do that at club level is obviously an issue.”
“It has been a tough two weeks for the club,” added Sheens.
“We have had a lot of disruptions and a number of injuries and those things are continuing.”
“We just have to fight our way through this period. We have got nine rounds and we have got to win enough games to hold our position and try to improve from where we are at the moment in eighth.
“It is not going to be easy. The Bulldogs are running second, two wins in front of us, so it is a pretty tight competition. Winning this game is not going to ensure us of a semi-final and losing is not going to put us out.
