It's long been a cliche, a fighter saying he's willing to die in the cage. For Mark Miller, he never knew how close he could have been to making that literal.
At 39, Miller returns to the fight game on Saturday in Moscow in a kickboxing match at the Ultimate Glory World Series. But his comeback, fighting for the first time in more than five years, has little to do with his age. The nearly foot-long scar down the center of his chest tells the bigger story.
When Miller gets in the ring against Nikolaj Falin, he will become the first known professional fighter to return after open-heart surgery.
