Rountree (13-6 MMA, 9-6 UFC) made an unsuccessful bid at the light heavyweight title Saturday in a fourth-round TKO loss to Alex Pereira (12-2 MMA, 9-1 UFC) at Delta Center in Salt Lake City. He started the fight strong, but the champ took over as the rounds wore on until he forced the finish.

One of the most remarkable runs in UFC history continues, but after much more difficulty than expected. Alex Pereira methodically broke down a game Khalil Rountree Jr. and used a bruising sequence of body punches to retain his light heavyweight championship with a fourth-round stoppage Saturday night in the main event of UFC 307 at the Delta Center in Salt Lake City.
