RFO returned to Mansfield last weekend for “Mansfield Mayhem 12,” and put on one of the most exciting amateur cards of the year.

In the main event, Jake Anderson kept his winning streak alive with a third round submission victory over John Gunther. Other notable winners were “Karate” Mike Williams and Raymond Yanez, who both announced intentions to turn pro after their victories.

Up-and-coming fighters were also part of the card, as Kyle Cremeans followed up his five-second knockout with a slick armbar submission over Tyree Johnson, and Josh Longood kept his perfect record intact with a submission due to strikes over Brian Wilichowski.

Some select videos from the event are available below, and you can check out all of the “Mansfield Mayhem 12″ fights, as well as fights from past RFO events, on the RFO YouTube page.
