Danny Garcia has warned Shawn Porter that he is in for a "rude awakening".
The pair return to BoxNation on Saturday 8th September when they clash in Brooklyn for the vacant WBC World Welterweight Title - Garcia’s old crown.
Former IBF Champion Porter has never been stopped, but his Philadelphia rival warned: "I've knocked out a lot of fighters for the first time, so it won't be surprising to me if I knock Shawn Porter out for the first time.
"Once you're in there with me, it's not the same as anyone else. It's not the same as what you expect it to be. You're in for a rude awakening," he said at Wednesday's media workout.
Garcia has won 34 of his 35 fights, with 20 coming inside the distance, and has also held the WBA and WBC belts at Super-Lightweight when Amir Khan was a victim.
He added: "This is another opportunity to become a four-time World Champion and that excites me. I still feel like the WBC Title is mine, so I'm even more ready to reclaim it.
"Getting that World Title back is what it's all about. I know that I'm always going to be a top fighter. I fill the seats and make big fights, that's why Shawn came to me after my win against Brandon Rios for his moment of glory.
"I can't rank Porter against the other top fighters in my career. I'll have to see what he brings once we get in the ring. I've fought a lot of great opponents and he's just the next in that line."
