Warren threatens to take legal action
Former two-weight world champion Haye has signed up to face Chisora on 14 July at Upton Park – a grudge match which is taking place under a licence from Luxembourg as neither fighter holds a British licence.
The domestic sport’s governing body said last month that all those involved in the show would instantly have their licences stripped without a hearing.
Warren said in a statement on www.frankwarren.com: “I still take the Board’s threat to call me to account for my role in the fight as Dereck Chisora’s manager as unlawful.”
