Sources close to the situation have informed Boxingtalk.com that an agreement in principle has been reached between Lou DiBella and Shelly Finkel that has Sergei Lyakhovich on the verge of officially replacing IBF heavyweight champion Chris Byrd, as Wladimir Klitschko's opponent on April 23. This should be no surprise to Boxingtalk.com readers since we first mentioned Lyakhovich as a probably replace when we broke the news regarding the implosion of both Klitschko bouts over the weekend. Klitschko advisor Shelly Finkel described Lyahkhovich as a "possibility" and says he'll be able to officially announce something tomorrow. Finkel did explain to Boxingtalk.com that Chris Byrd turned down $3.5M to face Wladimir in Germany, and rather surprisingly, Finkel also told Boxingtalk.com that Byrd is also refusing to accept $2.5M to face Wladimir in America! If Byrd doesn't have a complete change of heart overnight, there's no doubt, he'll be watching Wladimir Klitschko taking on weak opposition on HBO come April 23. Lyakhovich promoter Lou DiBella was unavailable for immediate comment. Stay tuned for all the latest. Remember Where You Heard It First! (7:00 PM ET)
