Anthony Joshua has laughed off Jermaine Franklin’s threat of a knockout ahead of their much-anticipated bout on Saturday 1 April and instead insisted this is the “worst time” to face him. The former heavyweight champion will make his return to the ring at the O2 Arena but for the first time since 2015, no world title is on the line.Joshua is looking to bounce back following consecutive defeats by Oleksandr Usyk and he faced his American opponent on Wednesday afternoon at a press conference in Portland Square.
