In a sport where one loss can forever change the outlook of a fighter’s career, Jay Hieron was once considered the future of the 170-pound weight class before future champ Georges St. Pierre handed him his first professional loss in 2004. Since that time, Hieron has clawed his way back to prominence while competing for every top promotion outside of the UFC, defeating the likes of Jake Ellenberger, Jason High, Jesse Taylor, and Joe Riggs. He is undoubtedly one of the most underrated and underappreciated welterweights in the world.

Building off of a solid wrestling base honed during his time as a Junior College National Champion at Nassau Community College in New York, Hieron has evolved under the tutelage of trainers at Xtreme Couture into a well-rounded mixed martial artist equally capable on his feet and on the ground. The loss to St. Pierre marks the only time Hieron has been finished in a professional fight.

    Ever since moving to the continental United States to train full time in mixed martial arts (MMA) Brad Tavares has seen a tremendous leap in his development as a fighter.
