Penrith have been fined $20,000 by the NRL over an incident involving centre Jamal Idris against the Warriors.
NRL Head of Football Todd Greenberg announced the fine on Thursday and said it related to an incident in which the Panthers had failed to take Idris from the field for a concussion test after taking a heavy knock in a tackle.
"Players must be taken from the field for a SCAT test if they show any signs of concussion and this did not happen with Jamal," Greenberg said.
He said the NRL had suspended $10,000 of the fine. The Panthers will be liable to pay this if there are any further breaches of the concussion rules in the next 12 months.
"Overall, the clubs have supported our requirement for players who take head knocks to be taken from the field to undergo a concussion test," Greenberg said. "But we cannot let up and we cannot become complacent because player safety has to remain our priority."
Greenberg warned the NRL would continue to take a hard line on any breach of the concussion rules in the remaining weeks of the finals. He said the NRL had sideline technology and operators in place to assist club doctors determine whether players are displaying concussive symptoms during the finals.
"We expect the rules to be followed vigilantly in every match – no matter how important the game might be," he said.
