The body, and brain, of an individual who chooses a career in combat sports can only take so much before it starts to fight back.
For Ultimate Fighting Championship (UFC) veteran Mac Danzig (21-12), that battle is now over, with The Ultimate Fighter (TUF) 6 winner announcing his mixed martial arts (MMA) retirement after competing in the sport for 13 years as a professional.
Numerous "gym wars" over the years finally caught up with the 34-year-old fighter, who made the wise decision to call it quits after absorbing too many shots to the head, citing health concerns -- and self preservation -- as the motivating factors behind the difficult decision.
"After sustaining some pretty severe concussions last year, and me thinking about my future as a father -- my future as a person -- I don't want to have Alzheimer's or dementia when I'm older. I don't want to force this past what I'm capable of taking. I've been in it for a really long time [13 years professionally, 14 total]. My body feels really good otherwise -- I feel like I'm in great shape. But, taking shots to the head like that, and losing my ability to take punches and not go out, has been a major factor in my decision."
Danzig retires in the midst of a three-fight losing streak, which included a brutal knockout at the hands of Melvin Guillard at UFC on FOX 8 back in July 2013.
However, since he defeated Tommy Speer to win TUF 6, Danzig never truly reached his full potential inside the Octagon. In fact, he failed to win back-to-back matches after starting his UFC career back in 2007 with back-to-back wins.
He leaves UFC with a sub-par record (5-8), but on his own terms and, hopefully, 100 percent healthy.
With, as he puts it, "no regrets."
