Jermell Charlo knows who he’s siding with when it comes to the bungled Terence Crawford vs. Errol Spence Jr. undisputed welterweight championship.

Charlo, the undisputed 154-pound champion from Houston, recently backed his stablemate and fellow Texan Spence after talks between Crawford and Spence broke down earlier last month. Crawford mostly blamed Al Haymon, Spence’s advisor and the founder of Premier Boxing Champions, for the collapse in negotiations, saying that a lack of transparency from Haymon on certain financial matters was a major dealbreaker.

In a recent Instagram Live session, Charlo, who is also advised by Haymon, railed at Crawford, questioning the latter's “pound-for-pound” credentials and describing the Omaha, Nebraska native as being “jealous” and “scared” of Spence. Charlo and Crawford have butted heads before, especially after Crawford indicated that he would be interested in moving up to 154 to challenge Charlo.  

“Man, Crawford all over the place, dog,” Charlo said. “Matter of fact, we from Texas making Crawford popular. Shout out to the Charlo twins, Errol Spence for making Crawford noticeable in boxing. Cuz the mother---er ain’t fight in I don’t know how long. I don’t know how y’all still got him on the pound-for-pound. But I guess he won some kind of undisputed title when he was at 140. But it’s a whole ‘nother level when you take a notch up. Y’all people don’t really understand that because at 140 they don’t hit the same as 147 and once you get to 154, oh God, who the king?”

“Crawford’s just jealous,” Charlo added. “Crawford’s jealous cuz he ain’t got no money.

“Crawford, he scared of Spence and he don’t want to fight cuz he’s chicken, right,” Charlo continued. “He want to try and get to the money. Everybody over here chasing the bag. I hear you. I’m chasin the bag for my family here.”  

On Monday night, Charlo also took to his Twitter account to further castigate Crawford, apparently in response to an interview Crawford gave to Brian Custer on The Last Stand Podcast published on the same day. In the interview, Crawford was asked if he would be interested in a fight with Charlo to which he responded “Of course, I’d beat his ass any day. Easy.”

In his tweet, Charlo accused Crawford of “clout chasing” and disappointing boxing fans by failing to reach a deal to fight Spence. Charlo also referenced Bob Arum, Crawford’s former promoter and with whom he feuded before parting ways last year. Crawford subsequently sued Arum for breach of contract and racism.  

“Clout chasing is the new promotions,” Charlo wrote. “I guess you Should of listen to bob, mfer knew what he was saying. @terencecrawford. You had a chance to make history for your family. You let the boxing world down, don’t call my name unless u really wanna fight. It’s different at 154.”

Crawford responded by writing facetiously, “Hi @TwinCharlo, how you doing buddy”.

Charlo then responded by comparing Crawford to two-division titlist Demetrius “Boo Boo” Andrade, a talented fighter who has been unable to garner significant fights.

“Why u keep pissing off the boxing world with your stupidity, how long you think that window gonna stay open? Bud & boo boo got a lot in common,” Charlo wrote.

Charlo (35-1-1, 19 KOs) is set to defend his WBA, WBO, WBC, and IBF 154-pound titles against WBO mandatory challenger Tim Tszyu (21-0, 15 KOs) of Australia on Jan. 29 in Las Vegas.

Crawford (38-0, 29 KOs) will take on David Avanesyan (29-3-1, 17 KOs) on Dec. 10 at CHI Health Center in his hometown of Omaha.
