Tyson Fury has warned Deontay Wilder not to back out of their heavyweight rematch.
"I'm just maintaining my fitness really. I'm [as] fit now as I was then, the same kind of thing," Fury told BT Sport.
"I'm ready to fight. Wilder, let's get the fight made, don't s*** yourself now mate!"
Fury was dropped twice by Wilder in December. Both men agreed to a rematch as Wilder dashed Anthony Joshua's hopes of facing him at Wembley on April 13.
