The film Ip Man 3 also stars heavyweight boxer Mike Tyson.
According to a report on Hktopten, the boxer and Donnie Yen Chi Tan engaged in combat during filming.
Donnie's elbow accidentally hit the boxer's left forefinger, which Tyson later confirmed to be fractured.
Earlier when the film company arranged for a set visit, Tyson was seen with his finger bandaged.
Speaking of his injuries, Tyson said: "At first you only worry whether Yen Chi Tan will be hurt, no one ever considered my safety. Now I am injured and still no one would console me."
However, Tyson was very professional and did not become more cautious in his fight scenes due to the injury.
He even insisted on personally performing all of the scenes and received praise from the crew.
On the incident, Chi Tan said: "Tyson was very professional. During the shoot I knew I bummed into him but I didn't think it was that serious. We even continued to shoot. After the shoot he went to the hospital for an examination and realized it was fractured. I was truly very sorry!"
He and the former champion have worked together for over ten days and he felt that Tyson was very humble and smart. "Very professional, very nice, the collaboration has been very pleasant."
