Terence Crawford apparently still has a significant chip on his shoulder.

The now former undisputed welterweight champion from Omaha, Nebraska, couldn’t help but notice the attitude of some fans (or critics) toward him after the International Boxing Federation stripped him of his 147-pound title last week for his inability to comply with a mandatory defense against top-rated contender Jaron “Boots” Ennis.

The development means that Crawford is no longer the undisputed welterweight champion, which he achieved in July when he stopped Errol Spence Jr. in nine rounds to unify all four belts in the division. It is the second time Crawford has cleaned out an entire weight class, having done so at 140. Crawford is unable to fulfill the IBF’s mandate because he owes Spence a contractually mandated rematch. It is not clear when that fight will happen, however, as Premier Boxing Champions, the outfit that backs Spence and Crawford, will need a new broadcasting home by the end of the year after Showtime shuts down its sport department.

Crawford, who has never been shy about voicing his antipathy toward his critics, lambasted his detractors for suggesting he is “scared” to fight Ennis—a criticism that Crawford has long endured as it pertained to Spence.

“I see a lot of Spence fans mad at me and jumping on Boots sack now!” Crawford wrote in a post on X, formerly Twitter. “I love it (three cry-laughing emojis) this the same sh!t I got and heard for 5 years I was scared this and that. It’s ok everyone just [accept] it I’m great and yall mad about it.”

Crawford, 36, still remains the welterweight titleholder of the WBO, WBA, and WBC.

A rematch between Crawford and Spence could take place at 154 pounds, which is the weight class that Spence desires. However, while Spence has the right to call for a rematch, the choice of the weight belongs to Crawford. For his part, Crawford suggested immediately after his stoppage win over Spence that he would be open to fighting at 154.
