It's been nearly a year since Christy Mack suffered a horrific attack on August 8, 2014, allegedly at the hands of her former partner, MMA fighter War Machine, says the Huffington Post.

The photos and injuries are stomach-turning and detailed in the latest episode of HBO's "Real Sports with Bryant Gumbel" in a report by David Scott scheduled to air Tuesday at 10 p.m. ET. However, what is most alarming is that Mack is far from alone in her suffering.

While domestic violence in the NFL has been the focus of many media reports and much criticism, figures reported by "Real Sports" show that the rate of domestic abuse arrests among MMA fighters is more than triple that of professional football players.
