During the press conference, Parker's team offered £20,000 to any Joshua fan who "can produce credible video of [Parker] being dropped."
"Parker has never been dropped. Not as an amateur, in sparring or in his profession," said Parker's promoted, David Higgins
"He's beaten hard men like Carlos Takam, who never dropped him."
Higgins, and more recently Parker, have made a point of making reference to what they describe as Joshua's suspect chin.
Parker insists he has never been hurt in a fight or in sparring much less knocked down.
The 25-year-old Parker wants a 40 per cent share of the purse against Joshua, with revenue shared rather than a fixed fee, but has said he would accept 35 per cent just to get the fight made.
