Charles Radtke ’s power proved to be too much for Matthew Semelsberger at UFC Fight Night 247 , and it led to a quick win. Radtke (10-4 MMA, 3-1 UFC) tagged Semelsberger (11-8 MMA, 5-6 UFC) early in the opening round of the welterweight bout at the UFC Apex in Las Vegas, and he didn’t let up from there. He continued to put hands on a stunned opponent until the referee jumped in and waved it off a mere 51 seconds after the fight began. Although an argument could be made the fight should’ve been let go longer, the decision was made to wave it off.
