The fight is almost sure to land on HBO Pay-Per-View</p><p>"I had a meeting, I spoke with my family. The decision was made because I still feel good. I feel capable and I can probably do two or three more fights," Marquez told ESPN Deportes Radio.</p><p>Marquez says he was given two return options - Bradley or WBO interim-junior welterweight champion Mike Alvarado. He selected Bradley.</p><p>"They discussed two opponents for September 14: Mike Alvarado and Timothy Bradley. I like challenges, Bradley would be a difficult fight for me. Apart from being world champion it would be a challenge to fight him and win another big challenge title in a fifth division, which for me is something that fills me with pride to have the opportunity to try," he said.</p><p>This move by Marquez would leave Manny Pacquiao with the likely option of facing Alvarado on a date in October in Macau.</p>
