Extreme Rules is about to get a lot more painful, as Mark Henry will clash with Sheamus in an absolutely out-of-control pay-per-view slugfest on May 19.

The road to the ultra-intense matchup began just after WrestleMania, when Henry unleashed a vicious pair of backstage assaults on Sheamus during both Raw and SmackDown. Sheamus would strike back with an onslaught of his own, before mimicking Henry — using his fallen adversary’s own catchphrase against him as he proclaimed with a smile, “That’s what I do.”

It turned out that the provoking hijinks of The Celtic Warrior were just beginning, as he went on to embarrass Henry in both a Tug-of-War on Raw and Arm Wrestling Contest on SmackDown.

In response, the outraged Henry challenged The Celtic Warrior to go head-to-head at Extreme Rules, a call the Irish Superstar who loves to fight gladly accepted. On that very same night, however, the irate Henry would take things to a whole new level during Sheamus’ match against Wade Barrett — whipping his foe mercilessly with a belt.

Despite his tendency to bring a great deal of fun to WWE, Sheamus has shown time and time again that, once the bell rings, he is all business. Still, can the three-time World Champion overcome the unadulterated rage of The World’s Strongest Man? Or will the Extreme Rules pay-per-view provide the perfect launching point for Henry to send The Celtic Warrior into his own wing of The Hall of Pain. Find out Sunday, May 19 at 8/5 p.m. PT.
