Melbourne's Will Chambers and Canberra's Joseph Leilua were fined $1100 and $1350 respectively for grade one contrary conduct charges for punching at the weekend.

In the past such offences carried suspension which the NRL reviewed in the off-season, determining Grade One charges could be supplemented with a fine rather than suspension.

Morris said he hoped the rule change would not bring back the biff.

"[Punching] was banned for a reason and it's not a good sight in the game,” he said. “While there are a lot of old school blokes who don't mind it, it's not something you want the kids to see and try to repeat.”

"It's a shame it happened but we can get over it… I think everyone was just sick of watching cricket and wanted the footy back.

"[Sam] Kasiano got off and [Will] Chambers got a grade one so that's just the way it is sometimes," Tolman said on Monday.

"That's the reason they brought it (the fine system) in, to stop guys from missing big games for a grade one [charge].

"If blokes are going out there and punching every week then they'll have to change the rules but at the moment it's a good system and if you're willing to pay $1500 to not miss a game for something that's small and inconspicuous then that's a good thing for players.

"I think it's just one of those things in the heat of the battle and sometimes you get a bit frustrated, but overall I think it's a non-issue.”
