Fighting can carry a pretty stiff penalty in prison. Loss of privileges like the telephone, commissary or being in the general population. If the fight was bad enough to place him in solitary confinement (the SHU), he might be there for a few months. If the other inmate was injured severely, there is a likelihood he could lose good time credits and transferred to a higher security penitentiary.
