Boxingtalk.com has been informed that Don King Productions has inked heavyweight contender Shannon Briggs to an exclusive promotional agreement, with an eye towards matching Briggs against WBO heavyweight champion Sergei Liakhovich. Briggs has been in long discussions for a fight with IBF heavyweight champion Wladimir Klitschko, but evidently Briggs grew tired of waiting. Where this leaves Klitschko's November 11 HBO date at Madison Square Garden is unclear at the moment, but newly crowned WBC heavyweight champion Oleg Maskaev now appears to be in the drivers seat to land a coveted fight against Klitschko. Shelly Finkel, Klitschko's advisor is out of the country and unavailable for immediate comment. Briggs attorney, Michael Borao was also unavailable for immediate comment. More to follow.
