The WWE has yet to round out the card for the Royal Rumble on Jan. 25 at the Wells Fargo Center in Philadelphia, leaving several spaces open for talent to be showcased at one of the best events of the year.

Thus far, the only two matches announced for the show are the 30-man over-the-top-rope Royal Rumble Match and the WWE World Heavyweight Championship Triple Threat Match pitting champion Brock Lesnar against John Cena and Seth Rollins.

There have also only been six participants announced for the Royal Rumble Match including Roman Reigns, Daniel Bryan, Rusev, Bray Wyatt, Dean Ambrose and Bad News Barrett.

Looking At Odds of WWE Supestars To Win 30-Man Rumble Match

We here at Sports World News will look at four potential bouts that could be added to the show, with one of them likely being placed on the pre-show.

WWE Intercontinental Championship--Bad News Barrett (c) vs. Dolph Ziggler: Ziggler has yet to be brought back to the company as the "fired" angle is still being played out, but there are rumors that the "Showoff" will be reinstated on next week's edition of RAW.

Ziggler lost the belt to Barrett on the Dec. 5 edition of the WWE's flagship show, but he should be entitled to a rematch. Giving these two Superstars pay-per-view time to tell a story could provide one of the best bouts of 2015 thus far when all is said and done.

The Authority can even say that they are bringing back Ziggler for his rematch and if he wins he can also get his full-time job back as a way to add another layer to the bout.

WWE United States Championship--Rusev (c) vs. Ryback: Like Ziggler, Ryback hasn't been officially brought back yet, but that is also expected to happen soon. These two titans have been feuding for a number of weeks, but there has been no real payoff just yet.

Similar to Ziggler, The Authority can bring Ryback back into the mix with a chance to get his job back by feeding him to the mighty Russian. These two need some closure to their feud and this could be a nice jumping off point for Rusev if he does in fact face John Cena at WrestleMania 31 on March 29.

WWE Tag Team Championships Tag Team Turmoil--The Usos (c) vs. The Miz & Damien Mizdow vs. Los Matadores vs. Cody Rhodes & Goldust vs. Cesaro & Tyson Kidd vs. The New Day: The WWE can put all of its tag teams on display -- possibly on the pre-show -- by providing a tag team turmoil match for all parties to get involved.

This will be an elimination match and will provide the WWE a showcase for its revitalized tag division. The WWE can spring off various tag team feuds by using this match as a springboard to future storylines within the division.

WWE Divas Championship Fatal 4 Way--Nikki Bella (c) vs. Paige vs. Brie Bella vs. Natalya: These four ladies have divided into a feud with the Bella Twins at one end and the new duo of Natalya and Paige on the other.

The WWE could blend this into a Fatal 4 Way match where not only will the feuds continue, but the dynamic within the friendships could be in peril with the gold on the line.

The WWE presents the Royal Rumble live from the Wells Fargo Center on Sunday, Jan. 25 in Philadelphia.
