Michael Chiesa has become the first fighter to file a lawsuit against Conor McGregor following the Irishman’s attack on a bus chartering fighters from UFC 223’s media day.

TMZ were the first to report on Chiesa’s lawsuit in which he claims he suffered “severe emotional distress, mental trauma and/or bodily harm” as a result of “assault, battery and intentional infliction of emotional distress.”

Chiesa is also filing charges against the Barclays Center, the arena in which UFC 223 and its media day were held, due to a claim of a failure “to engage in proper security measures to protect the plaintiff and other patrons.”

McGregor was arrested after the April attack, a case in which he ultimately struck a plea deal for, in which he was filmed throwing a dolly through the window of a bus holding the former champion’s rival Khabib Nurmagomedov.

As a result of the smashed glass on the bus, Chiesa suffered cuts and lacerations to his face which forced ‘Maverick’ out of his UFC 223 bout with Anthony Pettis.
