Given the serious nature of the allegations we have taken the immediate step to deactivate Jonathan from all team activities. We will continue to closely monitor this as it develops and evaluate additional information as it becomes available."
Dwyer, 25, was pulled from Cardinals practice on Wednesday afternoon after police arrived to ask him questions related to the investigation into the allegations.

According to the advisory, Dwyer was interviewed and admitted to the incidents; however he denied any physical assaults. Police are also serving a search warrant at Dwyer's residence.
