There is a lot of buzz surrounding the event, especially with the huge double main event. The two top matches will see Brock Lesnar battle The Undertaker and WWE World Heavyweight Champion Seth Rollins go head-to-head with WWE United States Champion John Cena in a title-for-title match.

10 Booking Decisions We Want To See At SummerSlam

--Rollins may have his hands full with Cena on Sunday, but he took some time out to share his top five SummerSlam matches with The Players' Tribune:

5. Bret Hart vs. The British Bulldog (1992)
4. Shawn Michaels vs. Triple H (2002)
3. Edge and Christian vs. The Hardys vs. The Dudleys (2000)
2. Dean Ambrose vs. Seth Rollins (2014)
1. Seth Rollins vs. John Cena (2015)

--One highly-anticipated match at SummerSlam will see Cesaro battle Kevin Owens, and the WWE released a video of the "Swiss Superman" working out for the show.

--There has been a lot of speculation that Dean Ambrose may turn heel when he teams up with Roman Reigns to take on The Wyatt Family on Sunday, but nothing has been confirmed. Regarding that match, Reigns spoke with AMNY.com about teaming with his buddy "The Lunatic Fringe."

"It feels good to have small talk and inside jokes out there," Reigns said. "And to be able to laugh and watch Ambrose do something crazy, watch him freak out and start destroying stuff. It's such a good dynamic, I think it's going to be a great matchup. Anytime you put some Shield boys in the ring with some Wyatt boys, it turns into some magic and some hectic craziness, so hopefully we don't burn the whole building down in one night."

--WWE Hall of Fame announcer Jim Ross addressed rumors on Twitter about him attending SummerSlam and he revealed he won't be there due to not being invited. Ross' one-man show in New York City went up against NXT Takeover: Brooklyn on Saturday.
