Will The Deadman rise against Dean Ambrose and The Shield?

The Undertaker, Kane and Daniel Bryan unite against the common threat of The Shield in a massive Raw match.

On the April 22 episode of Raw, the extraordinary all-star team of The Undertaker, Kane & Daniel Bryan fell to WWE’s “Hounds of Justice” in an instant classic Six-Man Tag Team Match.

Watch The Shield arrive at London's O2 Arena in a helicopter

Tonight in the main event of a monumental edition of SmackDown, The Undertaker will return home to compete on the blue brand for the first time in nearly three years, taking on The Shield’s Dean Ambrose in a one-on-one fight for redemption.

The most volatile and erratic of the black-clad jackals has a chance to make one of the most impressive singles debuts in WWE history and do what 21 Superstars were unable to do at WrestleMania: defeat The Phenom. Will The Deadman’s scourge destroy Ambrose and The Shield? Or could this be The Undertaker’s last ride?

Who will survive the no disqualification showdown?

The bitter and personal rivalry between Alberto Del Rio and Jack Swagger continues on SmackDown.

In less than one month, Alberto Del Rio and Jack Swagger will challenge World Heavyweight Champion Dolph Ziggler in a whirlwind Triple Threat Match at Extreme Rules. But tonight, in the wake of their two brutal encounters  at WrestleMania and last week on SmackDown, the two No. 1 contenders will go head-to-head in a No Disqualifications Match.

In light of the lawless match stipulation that will open to door to the use of devious weaponry or outside interference from the likes of Zeb Colter and Ricardo Rodriguez, will either of the fierce competitors even make it to Extreme Rules?

Will Sheamus’ rekindled rivalry with Big Show prove more ferocious than ever?

Randy Orton teams with Sheamus against Big Show & Mark Henry in the main event of SmackDown.

Since falling to The Shield at WrestleMania, the tenuous alliance of Big Show, Sheamus and Randy Orton has quite simply imploded, reigniting temporarily dormant rivalries in the process. What’s more, the Irish Superstar has also drawn the furious wrath of Mark Henry.

Tonight, longtime foes and notorious heavy-hitters Sheamus and Big Show attempt once again to “work out” their issues as on Friday night on the SmackDown battleground.

Who will be left standing when The Celtic Warrior and The World’s Largest Athlete square off in what promises to be an intensely physical — and personal — fight to the finish? And will The World’s Strongest Man decide to play a role?

Will The World’s Strongest Man drop The Viper?

Mark Henry vs. The Great Khali.

Speaking of Mark Henry, just two days after facing The Usos, Santino Marella and The Great Khali in  a Gauntlet Match on “WWE Main Event,” the massive Superstar is now scheduled to battle WWE’s Apex Predator, Randy Orton, on SmackDown.

Although Henry’s ire and staggering strength have been primarily focused on Sheamus of late, he unquestionably has no soft spot for The Viper  — particularly after the 400-pound powerhouse helped Big Show overcome Orton and Sheamus one week ago on SmackDown. This will make for one dangerous showdown on the blue brand.

Who will win the “Battle of the Brits”?

The new United States Champion Kofi Kingston clashes with Intercontinental Champion Wade Barrett in a Champion vs. Champion Match on SmackDown.

No reason to dress it up, tonight’s matchup between Intercontinental Champion Wade Barrett and William Regal will be an all-out brawl.

The WWE Universe at London’s O2 Arena will certainly enjoy the hometown fight — and the treat of seeing Master Regal compete. But which British Superstar will pick up a precious victory in the U.K. when The Barrett Barrage meets the Regal Stretch?
