Jason Taumalolo and Tautau Moga have been fined 2,500 Australian dollars by North Queensland Cowboys for their part in an alleged egging spree.
The duo were among five players who have agreed to pay damages after admitting to an incident in Townsville last Wednesday.
Powerful forward Taumalolo and centre Moga were charged with wilful damage and are set to appear in court next month after they were said to have thrown eggs at cars ahead of the NRL finals.
And the NRL champions announced on Monday that they have hit the pair in the pocket.
Cowboys head coach Paul Green said: "Last week, I said that after we returned from our game in Melbourne, we would address this issue, which we now have, in consultation with the NRL and its Integrity Unit.
"While we can't get into the specifics of our own internal investigation due to some matters still being before the court, our players are extremely remorseful for their involvement.
"They know that they acted improperly and that they have hurt not only the people directly affected, but also the club's members, supporters and partners.
"We've taken the matter seriously as the players' actions were out of step with both the values of the NRL and the club."
Taumalolo stated: "I've taken the time to apologise for what I did on Wednesday night to my team-mates and now that our internal process is complete, I would like to apologise to those who were affected by the incident as well as the wider community, the fans and the members of this great club.
"I know a lot of kids look up to me and I just don't want them to think it's the right thing."
Moga added: "I'm very sorry for letting the club and this great organisation down and I really want to apologise to those I've directly affected with my actions."
