Welterweight contender Ryan Garcia has issued a firm warning to upcoming opponent and former world champion, Rolando 'Rolly' Romero.

Romero is well known for his trash talking tactics to rile up his opponents.

And if he 'crosses a line' with his verbal swipes - Garcia has promised to shut him up by force.

"Rollie’s Ima let you know through this tweet and I hope you understand this truly, I’m not taking you lightly at all, I’m coming with some real f---ing anger and I’m sorry it has to be you, you can say all the funny sh!t you are going to say Tuesday, but if you cross the line Ima slap the f--- outta you. I promise you," Garcia stated on social media.

"You are here to be f---ing funny that’s it, funny is what got you here so don’t change course, grandpa had your ass fighting for your life and Pitbull had you looking for Easter eggs in the ring. And I’m have you lay your gloves down in the ring like an MMA fighters retiring!!!"

Garcia, Devin Haney and Teofimo Lopez will kick-off a two-city Press Tour this Tuesday, March 4, in New York, ahead of a spectacular three-fight card in Times Square, New York on Friday May 2, as Ring Magazine presents its first-ever event in the United States titled “FATAL FURY: City of the Wolves”, brought to you by SNK Corporation in association with Oscar De La Hoya for Golden Boy Promotions and Eddie Hearn for Matchroom Boxing.
