Earlier, Boxingtalk ran a story in which Omar Sheika complained that Jeff Lacy was avoiding him for a December 2, 2006 HBO date supposedly belonging to Lacy. Now representatives of Yusaf Mack have come forward with similar claims that the former IBF super middleweight titlist is ducking an opponent. Percy "Buster" Custis, who is Mack's claims that Team Lacy offered Mack a fight but subsequently rescinded the offer.  "Don't offer us a fight and then turn it down," said the angry Custis.  "HBO and Lacy are playing games.  They are scared."  Mack has a pro record of 22-1-2 with 14 KOs. Like both Lacy and Sheika, Mack is coming off a loss, in his case a sixth-round stoppage by Alejandro Berrio. Lacy was dominated by Joe Calzaghe in a world championship unification bout and Sheika is coming off losses to Lacy and Markus Beyer, both world titlists at the time. Therefore, positioning and performance will be enormously important as they prepare for their respective comeback fights.  As Boxingtalk understands, Mack is ready and willing to take on Lacy whenever and  wherever.
