WBC welterweight champion Shawn Porter is less than a week away from his unification with undefeated Errol Spence, who holds the IBF world title.
The two beltholders will collide this coming Saturday night, at the Staples Center in Los Angeles, California.
Spence is coming off a one-sided twelve round unanimous decision win over Mikey Garcia, who was moving up by two weight divisions.
Porter won four bouts in a row since his last defeat, including a tough split decision victory over Yordenis Ugas back in March.
Porter is the better underdog, with most experts siding with Spence to win the contest.
"Shawn Porter is going to leave the ring with two belts. I'm going to hit him. I'm going to hit him hard and I'm going to do things you've never seen anyone do against Errol Spence. I'm expecting there to be adversity for Errol. There's going to be a moment where he realizes he's losing this fight. He has to be solid psychologically. I don't know if he's going to be in the ring. I believe I have the advantage there and that I know how to get into his head," Spence said.
"I think Errol's confidence is natural like mine. But I think that he's fed his confidence to the point where some arrogance has come out. I think he's going to show that in the fight early on. He's going to have to adjust. Once he recognizes that, I expect the arrogance to go out the window and that he'll have to figure it out.
"I've never seen Errol go through any adversity in the ring. I don't think anyone has been able to challenge him the way I can challenge him. I'm really looking forward to it. I don't think there's too much to figure out with Errol. The game plan is to make him make the adjustments. Things don't always go to plan, but I still think I know what he wants to do in there. He's not going to give you a lot to adjust to, but what he does do, he's supreme and he's great at."
