WWE SummerSlam 2015 is set to begin at 7 p.m. ET at Barclays Center in Brooklyn on Sunday night. The show has been extended to four hours, and while fans can order the event on pay-per-view for $54.99 in HD, it can also be seen on the WWE Network.

Fans who are already subscribed to the WWE Network pay $9.99 per month, but new subscribers will be able to watch Summerslam for free. Fans who sign up for the Network on Sunday won’t have to make a payment until Sept. 23, getting the first month for no charge.

The Undertaker vs. Brock Lesnar will headline the show in a rematch from WrestleMania 30. John Cena and Seth Rollins will meet in the co-main event with both the WWE World Heavyweight Championship and the United States Championship on the line.

The Miz and Big Show will challenge Ryback for the Intercontinental Championship, and The Prime Time Players will defend their tag team titles in a fatal 4-way match. There are rumors that the tag team match could be moved to the pre-show, which begins at 6:30 p.m. ET.

The Divas Championship won’t be defended. Instead, nine divas will square off in a three-team elimination match.

Multiple celebrities outside of the wrestling world will be featured at SummerSlam. Stephen Amell, star of the TV show “Arrow,” will team with Neville in a match against Stardust and King Barrett. After recently leaving “The Daily Show,” Jon Stewart has been named the host of SummerSlam. Stewart made an appearance on “Monday Night Raw” on March 2.
