I'd go out on a limb and say... yes.
These people are professional athletes. Being paid for their skill, athleticism, professionalism, attention to training etc.
To get pissed (to that level) during a competition season (ie after you've started training for that season) is probably risky behaviour, that has resulted in the punishment.
The player had a choice about his behaviour - with this punishment (stood down until trial) more players might think about their choices, and the impact on their professional lives. If they don't like the sacrifice at this elite, professional level, choose a different profession, or run around in park footy and get pissed all you like.
