He is innocent until a court finds him guilty. However, given his high profile as an NRL player and the image the code and his employer, the Roosters, wish to put forward, the latter are under no compunction to select him to play. The Roosters beat a pretty decent side by 24 points yesterday, so its not like they desperately need him.
If he's found not guilty, the club would be bound to pay him his normal contract moneys. So it's not a case of an innocent player losing financially anyway.
The maximum penalty for Assault Causing Actual Body Harm is 5 years imprisonment, or 2 years if dealt with in a Local Court. He's also been charged with Common Assault, 10 charges in all. The complainant has standing and it would seem the case against him is reasonably strong. I doubt he'll do time but with the current campaign against domestic violence (and rightly so) it couldn't have come at a worse time. I suspect the Roosters and the NRL will wipe him like a snotty nose if he's found guilty.
