The deal between organiser WWE and Virgin Radio, brokered by Carat Sponsorship, will involve two listeners going head to head each weekday morning - refereed by O'Connell - to identify real and fake wrestling names.
The four callers who guess the most names will wrestle it out at the end of the week wearing inflatable suits in London's Golden Square. The champion will be taken to see WWE Wrestlemania live in Las Vegas, New York and Detroit.
Wrestlemania 23 will be live on Sky Box Office on 1 April and the radio promotion will be accompanied by a branded micro-site on www.virginradio.co.uk.
