BROOKLYN, N.Y. – Gervonta Davis glanced at the crowd and pointed to the hulking man in the oversized glass and tailored suit.

“What’s that guy’s name here, with the glasses on? Larry?” Davis said. “I worked with him my last camp. I see what he do. We know what he do.”

Larry would be Larry Wade, a strength and conditioning coach based in Las Vegas who has worked closely in the past with champions such as Shawn Porter and Caleb Plant.

At a press conference to usher in Davis’ May 28 Showtime Pay-Per-View fight against Rolando Romero, Davis took aim at Romero’s training handlers, suggesting he knew all the tricks up their sleeves.

In the case of Wade, Davis had worked with the coach when Davis was brought in as a sparring partner to help Porter prepare for his welterweight title bout against Terence Crawford last November; Porter ended up getting stopped in that fight in the 10th round.

Now Wade is in the corner of “Rolly” Romero, a big, brash, young lightweight who packs a powerful punch but is otherwise untested.

Romero brushed aside the idea that Davis had picked up on some sort of trade secret while working with Wade.

“Larry trains with Shawn Porter and Tank was with Shawn Porter for two weeks for the last fight, so it’s just that they did the same workouts together, but it’s not like Larry trained them, you know?” Romero told BoxingScene.com.

Davis also singled out Bullet Cromwell, the head trainer of Romero, during a Q&A hosted by Brian Custer, saying, “We know what Bullet do,” which led to an entertaining, expletive-laden exchange.

“You don’t know sh!t about me,” Cromwell fired back.

Romero said Davis should be concerned with his own training regiment. Furthermore, if he was so knowledgeable of other fighters’ training habits, why was his conditioning in past fights, as Romero put it, so poor?

“Tank doesn’t have sh!t,” Romero said. “If Tank had training secrets he wouldn’t be f-----g tired every damn fight.”

Like Davis, Romero is also promoted by Floyd Mayweather Jr.'s eponymous company, Mayweather Promotions. But Mayweather was nowhere to be found at the presser, presumably because he was busy plugging his own fight – an exhibition bout in Dubai on May 14 – the same day, although his right hand Leonard Ellerbe was present, doing his best to remain neutral.

A heated face-off between the two fighters saw Davis rip into a comparatively docile Romero for two uninterrupted minutes.

Romero, who has talked a good game himself, said he was not impressed with the threatening displays and thinks he has already gotten under the Baltimore native’s skin.

“Tank is very soft,” Romero said. “Tank thinks he’s a gangster, but he’s actually a fairy and posts very fruity videos.

“He has a real big head. It’s gonna be really hard to miss. I feel very bad for him. He may be punch drunk after this. He can barely speak as it is. He’s gonna have severe brain damage.”

Romero (14-0, 12 KOs) was originally scheduled to face Davis (26-0, 24 KOs) last December, but he was hit with a sexual assault allegation that scuttled that opportunity. He was eventually cleared after a full investigation conducted by Las Vegas police.

Romero, despite his usual upbeat coarseness, looked a bit relieved.

“An opportunity can be taken from you,” Romero said.  I’m just grateful to be back here on Showtime"
