More likely than the Raw battle royal, someone in the Smackdown match gets taken out on Friday and this match need to happen to let someone else fill the spot. A likely candidate would be Heath Slater, maybe Justin Gabriel or (sadly) Daniel Bryan. I can't imagine them taking any of the other five out of the match.
Participants for battle royal: Brodus Clay, Drew McIntyre, Ezekiel Jackson, Hornswoggle (sadly), Jey Uso, Jimmy Uso, Jinder Mahal, Johnny Curtis, Skip Sheffield, Ted DiBiase, The Great Khali, Trent Barreta, Tyson Kidd, Yoshi Tatsu
I know I had Skip on the Raw match too, but he could return to either brand and it would make sense. However, I don't see him being as lucky if he returns Sunday on the Blue brand. Also, I could see Drew McIntyre furthering the lack of care put into the draft by going to the Smackdown after feeling underused on Raw and helping Smackdown get another potential star.
Sure, Smackdown is heel-heavy, but he's to most logical person to go over right now since all of the faces are in Raw's MITB match. Maybe Chris Masters, but I doubt it. Neither Skip nor Drew would win this one though. Even though my prediction hasn't had many matches, I think that he could be a very interesting MITB participant.
Winner: Jinder Mahal
Likelihood of happening: 30 percent
