Ultimate Fighting Championship (UFC) light heavyweight smashing machine, Anthony Johnson, has ripped through the promotion’s 205-pound division, laying waste to former division No. 1 contenders like Alexander Gustafsson and Glover Teixeira, among others, in the process.

But “Rumble” was just as dangerous as a welterweight (proof), despite a weight cut that often bordered on lunacy.

“When I was fighting at welterweight, I used to walk around at 210,” Johnson told Facebook fans during his recent Q&A. “When I fought Dan Hardy, I just came off knee surgery and I was up to 230. I dropped down from 230 to 170 in two months.”

Extreme weight cuts can often have fatal consequences.

Not surprisingly, it was only a matter of time before his scale-defying experiment came to an end. In fact, it even reached the point where the 6’2” Johnson was unable make the middleweight mark.

After bouncing around the regional circuit for a few years, which led to his maturity as both a man and as a fighter, “Rumble” came storming back at 205 pounds, putting together a 6-1 record in UFC with five terrifying knockouts.

It was enough to earn him a rematch against light heavyweight champion Daniel Cormier at UFC 210 this weekend in Buffalo, New York, in what could be his “last chance” for division gold.
