Miami Heatâs mascot was knocked out cold by former UFC champion Conor McGregor during a mid-game skit promoting his pain relief spray, The Athletic reported. Although the skit seemed staged, with the mascot wearing gold boxing gloves, McGregorâs power punch unintentionally sent Burnieâthe man in the costumeâto the emergency room. A source briefed on the matter confirmed he has since gone home after being given pain medication. Videos show the mascot playfully taunting McGregor, mimicking MMA fighters. The ex-UFC fighter then cold-cocks Burnie to the floor, and McGregor then delivers a blow to him again on the basketball court as the announcer called out âMercy!â
