Newcastle Knights NRLW star Caitlin Moran is set to be investigated by the NRLโ€™s integrity unit after a social media post appearing to celebrate the recent death of the Queen.

The former Jillaroos and Indigenous All Stars representative posted an expletive-laden story to Instagram, calling the recently-deceased monarch a โ€˜dumb dogโ€™ in the process. The post was deleted eight hours after it was originally shared, but had already been spread far and wide.

Moran will now meet with the integrity unit โ€“ but not until next week, meaning she is free to play this weekend against the Sydney Roosters.

โ€œThe NRL became aware of the post on September 9,โ€ an NRL spokesperson told the Courier Mail.

โ€œThe Newcastle Knights were contacted immediately and enquiries commenced by the integrity unit.โ€

Moran will start at fullback for the high-stakes clash following the late withdrawal of Tamika Upton due to a lingering calf complaint.

The issue could be a tricky one for the integrity unit, given the historical impact of the British colonial era and the long-standing impact on Indigenous Australians.

But ignoring all of that โ€“ or maybe in spite of it โ€“ 2GB radio presenter Ray Hadley called it โ€œperhaps the most reprehensible thing ever seen connected to rugby league.โ€

โ€œIf she plays tomorrow, it will be a disgrace of monumental proportions,โ€ Hadley claimed on 4BC.

The winner of this week's clash will take top spot on the NRLW ladder, with the Roosters and Knights the only undefeated sides in the competition.
