Mac Danzig (Dave Mandel/Sherdog)‘Ultimate Fighter’ Winner Mac Danzig Retires; Cites Fear Of Potential Brain Injuries RJ Gardner March 5, 2014 News, Spotlight UFC veteran and and winner of The Ultimate Fighter season six, Mac Danzig, announced his retirement for competition via his Tumblr account. Dazing began his journey in mixed martial arts in 2000 when he dove headfirst into training. One year later Danzig made his professional debut defeating Cedric Stewart by split decision at Extreme Challenge Trials in Decatur, Ill. For six years Danzig paid his dues on the regional circuit before getting his big break on the sixth season of the hit UFC reality series, The Ultimate Fighter. Danzig went on to win the show finishing all four of his opponents via first-round submission. While in the UFC Danzig was never able to put more than two wins together but he was always competitive and be developed into an exciting fighter winning three performance bonuses in his last six fights. After 13 years in the sport, Danzig steps away with a 22-12-1 record, with 15 of his victories coming by way of stoppage. It is possible that Danzig would be continuing his career if it were not for the vicious knockout loss he suffered at the hands of Melvin Guillard in July of last year. Danzig stated in his Tumblr post that his brain was finally telling him to “chill out” and that he could no longer take the shots during his training. The accumulation of blows from training and fighting for 14 years had taken its toll on his body and he knew it was time to step away. Danzig plans to stay involved in the sport through the training and coaching of fighters as well as teaching seminars. He also looks forward to being able to spend more time focusing on his interests away from the cage.
