Along with UFC and Bellator this past weekend, the boxing world presented a championship fight.

Errol Spence Jr. retained his IBF title with a victory over Lamont Peterson. The card aired live on Showtime from the Barclays Center in Brooklyn.

Spence secured his 23rd victory in 23 pro fights with a stoppage prior to the start of the eighth round. Peterson’s trainer Barry Hunter, threw in the towel for his fighter.

A member of the 2012 U.S. Olympic boxing team, Spence out-landed Peterson (35-4-1) 161-45, while connecting on 49 percent of his power punches.

“I want to thank Lamont,” Spence said. “A lot of guys turned down the fight and he took it like a real warrior and I commend him for that. He’s a tough fighter. He’s willing to die in there.”

Following the win, Spence made it clear he wants Keith Thurman next.

“Everybody knows I’ve been waiting on ‘Some Time’ Thurman,” said Spence, looking ahead to a possible unification match with WBC and WBA Welterweight World Champion Keith Thurman. “Since I was 15-0 I’ve been calling this guy out and he keeps making excuses. Let’s get it on.He has two of the belts and we both have big names. It’s an easy fight to make and I want it.”

Thurman responded on Twitter:

Peterson had no issues with his corner calling a stop to the contest when they did.

“If he asks me to fight a million people, I will,” he said. “If he asks me to stop. I will stop. I will never question his decision. I know he has my best interests at heart.”

Hunter acknowledged the decision was a tough one, but stood behind it.

“It was really hard, but if you know Lamont, you know he was not going to give up,” Hunter said. “I had to stop it. At the end of the day, this is my son right here. There’s nothing more valuable than his well-being. If it comes to him or winning, I pick him. I care about him.”

Robert Easter moved to 21-0 with a split decision win over Javier Fortuna, defending his 135-pound title in the process.

“It was a tough fight, he’s a former world champion for a reason,” Easter told Gray. “We made it tough trying to counter punch. He wasn’t throwing much and it made it difficult for me to chase this guy around. I couldn’t get the knockout but we got the win and that’s all that matters. I knew he was going to run once he felt my power. He just wanted to grab and hold the whole fight.”

Marcus Browne pushed his record to 21-0 with a victory over Francy Ntetu and Adam Kowancki earned his 14th career knockout in 17 appearances vs. Iago Kiladze.

“I’m so thankful to all my Polish fans who come out and give me that extra support”, said Kownacki, who fought in front of hundreds of his compatriots. “I’m going to keep fighting for the fans and give everyone a great show.”
