WWE SummerSlam 2015 Matches: Latest Card Predictions, Including Cena vs. Rollins

With little over 24 hours to go until the biggest show of the summer, the anticipation levels are rising ahead of SummerSlam 2015.

A hefty 10 matches are scheduled to cover the extension of SummerSlam into a four-hour show, and with plenty of big names booked to appear and matches that will have a lasting impact on the future of WWE heading toward the latter part of the year, a dramatic night is expected in Brooklyn, New York.

But as the first bell approaches on Sunday night, let's take a look at some predictions for the high-profile matches on the card.

Kevin Owens vs. Cesaro

Arguably one of the toughest matches to call at SummerSlam involves two guys who have the potential to be anything they want in WWE over the coming years.

Losses to John Cena slowed Kevin Owens' momentum when he burst onto the main roster, but he has bounced back from that and looks to be in a good position again heading toward SummerSlam.

But he faces off against the guy who arguably has the most popular gimmick in WWE right now on Sunday night—Cesaro.

There are shades of Daniel Bryan's "Yes!" movement with all the "Cesaro Section" signs that keep popping up at WWE shows, with thousands of signs expected in Brooklyn this weekend.

But who wins the match itself? First of all, expect it to be a high-quality tussle between two wrestling thoroughbreds, and it could potentially be the longest match of the night.

It all boils down to whether Owens needs a win or not. It's probably too early in his WWE career to suggest he categorically needs to win, so perhaps the smart money might be on Cesaro to pick up the victory. If WWE is serious about turning the guy into a main eventer in the coming months and years, wins like this will be invaluable during his slow rise to the top.

It's tough to predict, but Cesaro might just be the slight favorite at the moment.

Brock Lesnar vs. Undertaker

The main event of SummerSlam is a match where literally anything could happen.

Will WWE choose to inflict a defeat on Brock Lesnar or Undertaker over a year after their dramatic meeting at WrestleMania XXX? That's tough to predict, because a loss for someone such as Lesnar in particular could be fatal for him moving forward.

So naturally, one can see WWE leaning toward a big twist to end SummerSlam and send the show off-air with a real bang.

You've got a couple of logical options to bring into the fold, too, notably the return of Sting and Undertaker's brother Kane.

Sting closing SummerSlam by confronting Undertaker and beating him down would be an incredibly dramatic move, and it would set up a forthcoming show such as Night of Champions superbly. 

But the other option, bringing in Kane, has a touch of storyline development behind it, given how WWE wrote The Big Red Monster off TV following a brutal attack involving Lesnar and some steel steps.

Whatever happens, the likelihood is that we could probably see a no-contest to finish off SummerSlam.

John Cena vs. Seth Rollins 

Another match where a controversial ending could take place is the WWE World Heavyweight Championship bout between Cena and Seth Rollins.

After all, the chances of Cena walking away with Rollins' title are not great, and the prospect of Rollins emerging victorious from the winner-takes-all bout with Cena's United States Championship also seems slim.

So it appears the ending to the match is going to have to be played out in a way that ensures both men leave with their respective titles.

How will WWE do it? The obvious and rather desperate answer includes interference from The Authority to deny Cena the top prize.

Rollins has become the master of screw-job finishes since winning the belt at WrestleMania 31, and having either Triple H come down to stop Cena or even bringing back J&J Security to beat down Cena is more likely than one of the two men winning clean.

Given how we're likely to see this feud become the headline bout in WWE over the next few months, a controversial finish here seems certain.
