Titans backrower Kevin Proctor has been suspended for four games and fined $20,000 after being caught using cocaine following Friday night's Anzac Test in Canberra.
The Gold Coast NRL board has also ordered he serve 50 hours of community service, and he'll remain stripped of his co-captaincy under further notice.
Titans CEO Graham Annesley conceded the 28-year-old's penalty could hurt the club on-field, but it was important to make a strong statement.
"The Board has taken a strong stance with Kevin despite his four-match suspension potentially damaging the club’s prospects over the coming month as we seek to remain in finals contention," he said in a statement.
"Of course, as a football club our priority is to win as many games as possible, but if we all have to suffer some pain in order to drive the message home, then so be it.
"We take our responsibility to the community seriously and we will not walk away from tough decisions just to increase our chances of on-field success.
“I am pleased to say Kevin has shown tremendous remorse since we first spoke with him last Sunday.
"Once again today he faced up to the consequences of his actions and accepted full responsibility.
"He also accepted the penalty handed down with good grace and apologised to the Board for everything he has put the club through in recent days."
