One of the most ferocious MMA fighters in his prime, Wanderlei Silva never shied away from standing and trading strikes with his opponents, even when he was standing in front of heavyweights heavy-hitters like Mark Hunt and Mirko Cro Cop. More than a decade later, he seems to be paying the price.
In a long interview with Brazilian website PVT, Silva says that he has many concussion-like symptoms after competing in martial arts for 29 years, from his first steps in muay thai to vale-tudo and mixed martial arts fights.
