Dak Prescott's pit bull is possibly facing the death penalty after attacking a neighbor in Frisco, Texas last week ... TMZ Sports has learned.
Prescott's dog, Icon, was quarantined last Monday after it escaped from the Dallas Cowboys QB's home and attacked a woman who was transported to a nearby hospital to be treated for her injuries.
Icon was supposed to be held in quarantine for 10 days -- which means it was scheduled to be released today -- but there's been a change of plans due to the seriousness of the incident.
Law enforcement tells us ... the case has been referred to the City of Frisco Municipal Court for a hearing to determine if the dog will be, or should be classified as a "dangerous dog."
If found to be dangerous, we're told there are multiple options on how to deal with it -- one of the options is euthanasia.
One official tells us the goal is to work with all parties for an amicable resolution -- but putting the dog to sleep is a real possibility. Another option could be removing the dog from city limits.
Unclear when the hearing is set to take place -- but we're told the dog will remain in quarantine until the outcome is decided.
