While filming Ip Man 3, crew members were afraid that Mike Tyson, who was a professional boxer, would forget the choreography and throw real punches to injure Yen. However, it was Yen who fractured Tyson's finger while using his elbow to block Tyson's punches.[50] Tyson has since said in various interviews that Donnie would beat him in a real fight. Yen remained humble and downplayed the entire event, claiming that it was purely an accident. [51]
