Eight matches were contested at the event (including with one match on the pre-show). In the main event, Seth Rollins defeated Randy Orton in a Steel Cage match to successfully defend the WWE World Heavyweight Championship.

The event was available on the WWE Network in over 140 countries and on pay-per-view had 56,000 buys (excluding WWE Network views), down from the previous year's 108,000 buys.

The professional wrestling matches at Extreme Rules featured professional wrestlers performing as characters in scripted events pre-determined by the hosting promotion, WWE. Storylines between the characters played out on WWE's primary television programs, Raw and SmackDown.

At WrestleMania 31, John Cena defeated Rusev to win the United States Championship, marking Rusev's first defeat since appearing on WWE's main roster. On the April 2 episode of SmackDown, Rusev invoked his rematch clause to face Cena for the title at the event. On the April 13 episode of Raw, following Cena's title defense against Bad News Barrett, Rusev attacked Cena with a chain and Lana revealed that the match between Cena and Rusev would be a Russian Chain match.
