Guerrero is out due to personal issues. I think it might involve his wife's health. Thoughts and prayers with Guerrero and his family. Diaz's team accepted Katsidis offer for a rematch. Whether it goes anywhere, that's another thing. The link from b scene mentioned Brendan Rios as a possible replacement for Katsidis.
Rios looked great on the wkend in defeating Jorge Teron on Top Rank's fox sports show. Katsidis would start favourite but i dont see much point in him facing Rios at this stage.
