Jarrell Miller in rude gesture to Derek Chisora as drug cheat fumes at Anthony Joshua pal after workout

JARRELL MILLER signed “f*** off” to old enemy Derek Chisora over his Anthony Joshua defence.

The 39-year-old British boxing warhorse has always hated the American for doping in the build-up to the cancelled 2019 AJ fight.

Chisora is like a big brother to the London 2012 legend, after they came through the same Finchley ABC gym and never called each other out.

Del Boy is here in Riyadh to support his protege in Saturday night’s must-win Otto Wallin bout.

And he was ringside at Wednesday’s media workout in the Kingdom Arena heckling the Brooklyn heavyweight from ringside.

Chisora was on the ring apron hurling insults as the 28st cheat.

And when his practice session had ended the USA jugger-naught exited on the opposite side of the ring and stuck a chubby finger up in Chisora’s direction.

Chisora will be bellowing support for Miller opponent and fellow Londoner Daniel Dubois on Saturday too.

Miller failed a handful of tests for a range of seriously dangerous substances before his crack at AJ and has never apologised for the scandal.

So Dubois will be a national treasure and a pal of Del Boy and Joshua‘s if he can execute a revenge mission for English boxing.

Elsewhere on the card, Joshua takes on Swede Wallin in the final fight of the night.

Before that, KO artist Deontay Wilder will face New Zealander Joseph Parker.

It is being reported wins for both Joshua and Wilder will lead to the pair agreeing a clash for March.
