Six minutes and forty seconds was the amount of time DaVarryl Williamson needed on Saturday night to knock out Derrick Jefferson at Madison Square Garden. Now, 22-3 with 18 knockouts, with one of the losses really more like a draw against Wladimir Klitschko, Williamson has sent out a press release that he has secured the #3 position in that sanctioning body's heavyweight ratings. The IBF itself has not yet confirmed this rating.  After such a short night's work, Williamson is eager for a quick return to the ring.  "I'm looking forward to coming back as soon as [promoter Don King] wants me.  If he needs me on July 23rd, I'll be ready. It doesn't matter whothe opponent is, I announced to the world that I am here and a force to be reckoned with."
