"I heard about the Usyk situation, and he's going to be there," Wilder said to Sky Sports. "I hold Usyk to be a man of his word.
"If Usyk's saying he wants to give me an opportunity for the titles, then that's what I'm holding his word to. I always tell people that I don't look past fighters, but I do look through them; there's nothing wrong with that, being confident in yourself and looking ahead once this chapter is closed."
Wilder looks to rebound after coming off back-to-back losses to Fury. It's the first time he'll compete in a little over a year. The 36-year-old knows that Usyk being there is a moot point if he doesn't beat Helenius.
"I've got to handle business at the end of the day," Wilder said. "Without handling business, then nothing else is moving forward. I'm taking it one fight at a time. I'm taking it all in one day at a time. Once I've accomplished and finished what I have to do with Robert, then I'll move on, and I'll be looking forward to the next challenge, whether it's Usyk or whether it's anybody else."
