In Dan Rafael's latest blog entry, he notes that some potentially interesting matchups are being discussed, including Juan Manuel Marquez-Juan Diaz (with a possible Marquez-Barrera rematch if that falls through) and Jermain Taylor-Lucian Bute. He also mentions that Berto-Mosley seems unlikely (not enough extra $$ for the risk of fighting Mosley instead of Collazo, plus he'd have to vacate his belt) and that Tarver actually did not have a rematch clause for the Dawson fight.
