Just to clarify...Tito didn't want to fight chuck the first time so Chuck and Randy fought. Randy won and was given an interim light heavy weight belt. That pissed off Tito, so then Tito and Randy fought. Randy won and that is how Tito lost his belt. Then Tito and Chuck fought (with no belt on the line) and Tito got knocked out at the beginning of the second round.
If Tito doesn't try to stand with Chuck he might be able to win. Otherwise Chuck will knock him out again. Overall I give Chuck a 65% chance of winning and Tito a 35% chance.
