Sullivan, too, has his horror stories. After training sessions, he says, "Sometimes I come home (and) I can't talk. I'm not going to lie. It's called being 'punch drunk.' You stutter your words.
"I've had it last as long as a day and a half. You're thinking the word, but you just stutter it. You have that slur to you and you're kind of like hazed. It literally feels like being drunk, only without the nauseous feeling."
Sullivan, who says he has had his nose broken twice while sparring, comes home two or three times during each fight camp having trouble speaking, according to Rusher, his fiancee.
"He'll want to say something but his mouth isn't moving as fast as his brain might be," Rusher says. "He looks, like, disoriented, like his head is floating."
During one savage sparring session with a bigger fighter, Sullivan says, his head was rammed through the drywall at Kurt Pellegrino's Mixed Martial Arts Academy in Belmar, the gym where he now does most of his training. Later that day, Sullivan says, a friend found him wandering through Target with deodorant in his hands.
"I don't even remember it," Sullivan says. "I was brain dead."
