Jaydn Su’A was binned for the second week in a row and it cost the Dragons dearly.
Su’A was controversially given his marching order for a late hit on Panthers halfback Sean O’Sullivan last week.
This time it was a high shot on Sharks star recruit Dale Finucane and Su’a was put on report for the 16th minute incident.
But not everyone was convinced he deserved the sanction which which proved a game-changing moment.
Sharks centre Jesse Ramien was binned in the 73rd minute for a high shot on Dragons forward Jack Gosiewski - but the score was already 36-6.
