The heavyweight duo will square off on September 28 in a mouth-watering all-British affair, and the 'Furious One' has stoked the fire ahead of the grudge match.
"I tell you what's going to happen. I'm seriously going to knock David Haye out," Fury told Sky Sports News. "I'm going to knock him dead spark out. Not even a contest. People have heard this talk before, but I don't say things [like that].
"Like I said to Steve Cunningham, I'm going to knock you spark out, you're a cruiserweight. Dave Haye is only a cruiserweight.
"You've got to give it to him, he's very fast, he's an explosive puncher and a former world champion, so it's going to look better when I knock him out."
Haye has not fought since he beat Dereck Chisora last summer, while Fury's last fight ended with a win against Cunningham in New York back in April.
