With Spadafora getting arrested again (and now possibly being under house arrest?) his trial for attempted homicide starting in Oct and apparently needing surgery on his elbow I think you can forget about him for now.
Time to stop fucking around here: the next fight needs to be the winner of Mitchell/Tszyu, Harris/Urkal or Cotto. There are enough options there for at least one of them to come off if there is enough determination to make it happen. If it takes 6 months to get one of these fighters in the ring, e.g. by having to force the mandatory IBF or WBO defence, then think about a warm up fight in between. Otherwise Stewart is the warm up and it time to get this show on the road.
