Springbok lock Johan Ackermann has taken over coaching the Lions.
Lions president Kevin de Klerk said the franchise was fortunate to have two experienced assistant coaches [Ackermann and Carlos Spencer] who could step in.
"We are formalising our case and will issue our disciplinary document some time this week," de Klerk told the Times.
"I want to make it clear that the decision to suspend John was not a knee-jerk reaction but a decision that came from a well-documented list of grievances.
"People forget that players are professional employees these days and, as such, have labour rights and are allowed to exercise those rights through the correct channels.
"I know it looks like John's position, regardless of the outcome of the disciplinary hearing, is untenable but I can't say that is definitely going to be the case.
"He needs to have his hearing, which is a legal right, and we can only go forward from there."
