But as has been explained above, the concussion rule isn't only applicable for foul play. It's any concussion. You'll have a team out on their feet, one point up, 10 minutes to go, and the most exhausted player will fake a concussion to bring on a fresh player, an unused 18th man, without even impacting their interchange.So what? It still isn't fair that some players get taken out by illegal actions and they lose the victim for the rest of the game while the offender is usually penalised but continues to play and MAYBE gets suspended.
Where is the benefit for the victim's team? We all know no one gets sinbinned or sent off anymore unless they are 30m onside.
