Junior middleweight contender Erickson Lubin is back in the hunt for a world title shot.

Last October at Barclays Center in Brooklyn, New York, Lubin was shockingly knocked out in the first round by WBC world champion Jermell Charlo.

The outcome was shocking to many, as the contest was widely viewed as one of the better matchups of the year.

Lubin (19-1, 14 KOs) returned this past Saturday night in El Paso, Texas and picked up a comeback stoppage win in four rounds.

When he faced Charlo, the young contender fought his way to a mandatory position to secure the shot.

He's now removing the outcome of the Charlo contest from his mind.

“When I was on the floor, trying to get up, I wasn’t conscious, but I wasn’t feeling any pain. It was just a flash shot. To watch [replays of] that was disturbing,” said Lubin to Premier Boxing Champions.

“The referee saw me fighting hard, and he discontinued the fight because he saw me struggling…fighting to get up. As he was walking me to my corner, I was like, ‘Oh my God, [expletive].’ I asked my coach, ‘What round was that?’ He was like, ‘Round 1’...That was heartbreaking to know that it was over.”

And he wants another crack at Charlo to get revenge.

Lubin has hope in securing that shot.

Last year, on the same card where Lubin suffered his first career defeat - Austin Trout suffered a stoppage loss at the hands of IBF champion Jarrett Hurd. And now Trout is coming right back in world title fight, against Charlo, on June 9th.

"I’m back and ready to regain that respect from my doubters and naysayers and to show I’m still one of the best fighters at 154 pounds. I’m definitely trying to make a statement. It’s definitely ‘Hammer Time’ once again," Lubin said.

“Trout’s back fighting for a title right after his loss to Jarrett Hurd, and I could maybe see something like that happening for me since I definitely want a rematch with Charlo. Or after this fight, maybe I’ll be in with another contender or I’d like a fight to become a mandatory challenger to one of the titles,” Lubin said.

“However it goes, I’m ready to go to war with any of the other talented fighters within the division. People might be doubting me, thinking I shouldn’t take a rematch with Charlo or that another title fight is too soon for me, but I’m young, I have a long career ahead of me, I’m ready to work my way back in, and I do not plan on losing ever again.”
