Antonio Tarver vs. Nagy Aguilera, on Showtime, October 15. It will be Tarver's heavyweight debut. Just waiting on a location to sign at this point. Aguilera has lost twice since upsetting Oleg Maskaev.
Vitali Klitschko vs. Tomasz Adamek, next year, at MSG. They're still in the early stages of talks for this one, but it would make sense for all sides, and HBO has expressed interest. In the interim, Adamek vs. Lance Whitaker seems likely at the end of this year.
Bernard Hopkins vs. Jean Pascal, December 18, on HBO. According to Richard Schafer, talks are progressing nicely. TV availability in both the US and Canada will determine the final date.
According to Dan Rafael, Mike Jones's likely opponent for the Pacquiao-Margarito undercard is Jesus Soto-Karass. Since decent names are involved, expect all three undercard fights to be showcase type bouts.
Adrian Diaconu will face Omar Sheika on the undercard of Lucian Bute against Jesse Brinkley. No U.S. TV date as of yet for that one, but I'd be surprised if it doesn't end up being available in the US somehow, even if only by internet PPV.
James Toney against either Antonio Tarver or Odlanier Solis. It's unclear what weight a Tarver fight would be at, but I have doubts that Toney could make 200 even if he tried. He's just let himself go for too long.
Devon Alexander versus Marcos Maidana, March 6, on HBO
Humberto Soto versus the winner of Valero-DeMarco. Soto should be ringside to call out the winner, and if Valero wins, Soto-Valero is probably the best fight Bob Arum can make.
Chad Dawson versus Jean Pascal, in June, in Canada. As noted previously, Pascal would need to heal from recent shoulder surgery before he could start training.
Albert Sosnowski versus Audley Harrison. Sosnowski won the European heavyweight title last weekend, and Audley's coming off a Prizefighter victory. I don't even want to think about either of these two getting in there with a Klitschko.
