Cronulla five-eighth Todd Carney’s future in the NRL is again under threat following the appearance of a disturbing image on social media.

The image published on Twitter on Saturday night shows Carney standing at a urinal and he appears to be engaged in an unsavoury act.

It’s the latest incident in Carney’s colourful career which has been marred by alcohol-related issues.

The 28-year-old NSW representative and 2010 Dally M medallist was banned from playing in the NRL in 2009 due to repeated alcohol-related incidents when he was at Canberra.

Carney joined Cronulla in 2012 after being sacked by the Sydney Roosters for breaking a club-issued alcohol ban in 2011.

He linked with the Roosters following a year playing rugby league in regional Queensland.

This latest incident comes after Carney starred for the battling Sharks in their thrilling comeback win over Brisbane on Friday night.
