Brock Lesnar's return on Sunday night was kept so under wraps that even the participants in his match didn't know he was going to win.

Surprising wrestling fans nowadays is extremely difficult. Thanks to the existence of camera phones and social media, pretty much everything leaks out somehow. However, every now and again, promotions pull off a genuine shock. Recent examples include Chris Jericho showing up in New Japan, The Hardy Boyz WrestleMania return, and Brock Lesnar ending The Undertaker's streak.

WWE managed to pull off another Lesnar surprise on Sunday night. As Money In The Bank's main event came to its conclusion, The Beast's music hit. Lesnar then proceeded to march to the ring, dumped Ali off the ladder, and ascended it himself to lay claim to the MITB contract. So how exactly did WWE manage to prevent word of Lesnar's participation from leaking?

Well, for starters, they told absolutely nobody about it. That includes the seven men in the ladder match. According to PWInsider, the Superstars were told that Ali would be winning the briefcase. Then, right before the match was about to begin, they were then told that wasn't the case. Instead, an unnamed eighth man would come to the ring late on and win the match.

As you can tell from the look on people's faces at ringside, most notably Randy Orton, Lesnar being the mystery participant did not go down well. Ali will have been the one most annoyed with the result. Believing he was going to become Mr. MITB only to have that dream snatched from him seconds before making his way to the ring. Despite rarely being outspoken about this kind of thing, he did make his feelings known on Twitter as you can see above.

This kind of thing really is a double-edged sword for both WWE and its fans. Creative managed to pull off a genuine surprise, which is hard to do. On the other hand, WWE also had to screw over a good and much-loved guy in Ali in order to do so. We feel like Ali should have been clued in to what was going to happen. However, if news of Lesnar's return and win had leaked, the finger of blame would have been pointed firmly at Ali.
