"Todd is very, very aware, with various meetings with myself, his manager David Riolo, his family - who have been very supportive - and even with the NRL today, of where he stands and the consequences he faces if he doesn't fulfil his commitments as an NRL player," Flanagan said.
"It's his last chance from the NRL's point of view. We'll assess what he does here in his time at the Sharks - he starts fresh today with us. All that stuff that's gone on before, it is history and we've got to deal with it and assess it, but we start fresh today."
Gallop said he was encouraged by Carney's commitment to getting his career back on track, and was hopeful the 2010 Dally M medallist could return to playing with the type of form that had him ranked among the game's best players less than a year ago.
"[Cronulla are] making a big investment in him, the game is making a big investment in him, he needs to take responsibility for that," Gallop said.
"Today was about encouraging him to take that opportunity.
"He's excited about being in an NRL club again and playing footy again, he needs to focus on that and avoid risky situations, and I think he understands that as well."
Carney is expected to join teammates at an induction day at the club next week before starting pre-season training on November 7.
