Things weren’t exactly going Jeremy Stephens ’ way against Jimmie Rivera – until he changed that with one punch. Making his bareknuckle boxing debut, Stephens earned a doctor’s stoppage TKO over fellow former UFC standout Rivera on Saturday night at BKFC 56 in Salt Lake City. The fight was called after the third round when Rivera suffered a nasty laceration over his left eye thanks to a Stephens uppercut. It was a disappointing end for Rivera, who was effective through two rounds as he attacked both the head and body and appeared to be the quicker fighter.
