WWE SummerSlam 2015 was built to be the biggest event in the pay-per-view’s history, and it certainly featured its share of surprises. A celebrity helped determine the outcome of the PPV’s second-biggest match, while the main event ended in controversy.

Jon Stewart was the host of SummerSlam, and he got involved in the championship match between John Cena and Seth Rollins. The Undertaker technically got his win back from Brock Lesnar after losing to the former UFC Champion at WrestleMania 30. But The Undertaker cheated to win, and Lesnar should’ve been ruled the winner just seconds prior.

Below are the complete results for the PPV, including a quick recap of all 10 matches on the card.

Brock Lesnar vs. The Undertaker

The main event was far more entertaining than their WrestleMania 30 match, but it ended in awkward controversy. The timekeeper rang the bell when Lesnar had The Undertaker in a Kimura Lock, even though the referee didn’t signal that the Deadman had tapped out. When the ref made it clear that the match was not over, The Undertaker delivered a low blow to Lesnar and used his Hell’s Gate submission to make Lesnar pass out. But after The Undertaker headed backstage, a look at the video replay showed that The Undertaker did initially tap out when the first bell rang. The conclusion leaves the door open for another match between The Undertaker and Lesnar, possibly at WrestleMania 32.

Winner: The Undertaker

Seth Rollins vs. John Cena (WWE World Heavyweight Championship vs. United States Championship Match)

Many didn’t expect a decisive conclusion to the match with two belts on the line, but Rollins became the first person to ever hold the WWE World Heavyweight Championship and U.S Title simultaneously. The two champs had maybe the best match of the night, and Cena was ready to win his 16th world title when he hit Rollins with an Attitude Adjustment. But the ref was knocked out when he bumped into Cena, allowing Rollins to stay in the match. Jon Stewart used this opportunity to run down to the ring and hit Cena with a chair. Rollins Pedigreed Cena onto the chair, pinning him for the win.

Winner: Seth Rollins

Bray Wyatt And Luke Harper vs. Roman Reigns And Dean Ambrose

The heel turn that was expected from either Reigns or Ambrose never came, and the former Shield members teamed up to beat two-thirds of The Wyatt Family. A hard-fought match concluded with both Ambrose and Reigns hitting their finishers. Reigns was booed by the Barclays Center crowd when he hit Bray with a spear for the victory.

Winner: Roman Reigns and Dean Ambrose

Kevin Owens vs. Cesaro

Owens and Cesaro preceded the main event, and they put on one of the best matches all weekend. Cesaro put on a few impressive feats of strength, as he often does. But it was Owens who won clean, hitting a Pop-Up Powerbomb for the win.

Winner: Kevin Owens

Randy Orton vs. Sheamus

Having lost to Orton clean at WWE Battleground, Sheamus returned the favor at SummerSlam. Mr. Money in the Bank delivered back-to-back Brouge Kicks to end the match.

Stephen Amell And Neville vs. Stardust And King Barrett

The star of “Arrow” looked about as good as any celebrity has ever looked in a WWE match. He spent a decent amount of time in the ring, taking bumps and eventually, jumping off the top rope to take out both Stardust and Barrett on the outside of the ring. Neville pinned Barrett after hitting the Red Arrow.

Winner: Stephen Amell And Neville

Dolph Ziggler vs. Rusev

This was the only match of the night that didn’t end with a conclusive winner. Both Ziggler and Rusev were counted out, as Ziggler made his way back into the ring just after the ref counted to 10. Lana and Summer Rae got involved in a scrum after the match, likely leading to a mixed tag match at Night of Champions next month.

Winner: Double-Count Out

Team Bella vs. Team B.A.D. vs. PCB (Three Team Elimination Match)

One night after Sasha Banks lost her NXT Women’s Championship, her team was the first to be eliminated when Brie Bella pinned Tamina Snuka. But it was PCB that ended the night on top, as Becky Lynch pinned Brie for the win.

Winner: PCB

Ryback vs. Big Show vs. The Miz (Intercontinental Championship Triple Threat Match)

Ryback retained his title in the quickest match on the card. After Big Show took out The Miz with a Knockout Punch, Ryback tossed him out of the ring and pinned The Miz for the win. Since Ryback didn't pin Big Show, the two could have a singles match for the title in the near future.

Winner: Ryback

The Prime Time Players vs. Los Matadores vs. The Lucha Dragons vs. The New Day (WWE Tag Team Championship Match)

The New Day won back their championships in one of the best matches on the card. After it looked like Titus O’Neil might get the win, Kofi Kingston snuck in and pinned a member of Los Matadores, having tagged himself back into the match just seconds earlier.

Winner: The New Day
