A video has surfaced online that depicts a commercial for WWE's SummerSlam pay-per-view on Aug. 17 at the Staples Center in Los Angeles, possibly spoiling the planned Brock Lesnar vs. John Cena main event.

The commercial depicts Lesnar as a former UFC Champion taking on the WWE World Heavyweight Champion in Cena in the main event at SummerSlam.

This is the second time something has leaked that has spoiled the WWE's plans for the main event as Amazon leaked a SummerSlam 2014 DVD cover with Lesnar and Cena depicted on it.

WWE Splits Cesaro And Heyman In Prep For Lesnar's Return

Cena is slated to face Randy Orton, Roman Reigns and Kane in a Fatal 4 Way match at Sunday's Battleground event and Triple H has promised a "Plan B" for Cena if he should get through the match while Paul Heyman, Lesnar's manager, hyped a "Plan C."

It is likely that Triple H's Plan B is "Mr. Money in the Bank" Seth Rollins, who had an injury scare at RAW but is still expected to face Dean Ambrose at Battleground Sunday. Heyman's Plan C likely planted the seeds for Lesnar's return to action.

Lesnar is expected to come back from his hiatus fresh off of ending The Streak of The Undertaker at April's WrestleMania XXX to face Cena in the main event of the second biggest show of the year. Heyman and Cesaro were split up on RAW in order for Heyman to set his sights back on Lesnar.

Heyman and Cesaro may just be temporarily split up, but for now Cesaro will go his own way and he is entered in the Intercontinental Championship battle royal at Battleground while Heyman will guide Lesnar into SummerSlam for the main event.

There were reports that Lesnar will likely win at SummerSlam then lose the title back to Cena or to someone else at Night of Champions on Sept. 21 at the Bridgestone Arena in Nashville.

Lesnar vs. Cena is expected to headline the biggest WWE event of the summer.
