Joseph Parker's camp have gone on the offensive against fellow world champion Anthony Joshua, saying he has a "glass jaw" and will fold at the first sign of pressure like the England team at a football World Cup.
Parker, promoter David Higgins and trainer Kevin Barry will this morning give an update on negotiations on a showdown between the New Zealand heavyweight, the WBO world champion, and IBF and WBA world title holder Joshua, but in the meantime Higgins has gone for the jugular.
In a statement to media, Higgins said he would reveal in an exclusive video over a minute long which shows Joshua, an Olympic gold medallist, being continually knocked down in sparring.
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.
