Light heavyweight James McSweeney spent a good deal of his career training alongside UFC champion Jon Jones as part of Greg Jackson’s camp in New Mexico. In addition to polishing his craft alongside Jones, the 31-year old also apparently picked up some crime-fighting techniques as well.

McSweeney was in Las Vegas this week with family when he witnessed a man attempt to rob a vendor at knifepoint. Rather than allow things to unfold in front of him without intervening, the TUF 10 alumnus decided to act without concern for his own well-being.

“I didn’t want anyone to get hurt, so I just went over and grabbed from the side by his shoulder and his lapel and took the knife from him and swept him to the floor and pinned him to the ground until security came and handcuffed him and took him off,” said McSweeney in an interview with MMAWeekly. “I knew I had the capabilities to stop it, so I tried to stop it. I mean if they pull a knife, you have to assume they have intentions to use it so that was my reaction. I didn’t want anyone to get hurt.”

Though released by the UFC after losing back-to-back bouts, McSweeney has since bounced back some career-wise by notching wins in six of his last seven scraps. He holds an overall record of 10-9 with all of the victories involving some form of finish.
