The UFC Vegas 28 main card is almost over and saw a handful of decisions, including a classic banger between Santiago Ponzinibbio and Miguel Baeza, but the co-main event did just witnessed a first-round finish. The UFC’s #11 ranked heavyweight, Marcin Tybura, stopped the #8 ranked, Walt Harris, with ground strikes towards the end of the opening round. Harris started strong, putting Tybura through a dangerous storm of explosive strikes that had him wobbled, but once Tybura got the fight to the floor, it was only a matter of time. Tybura worked his way to the back and kept punching away until the referee intervened.
