Coming out of the WWE SmackDown tapings on Tuesday night, more names were added to the 30-man elimination match at the Royal Rumble this Sunday live from the Wells Fargo Center in Philadelphia.

Dolph Ziggler defeated Intercontinental Champion Bad News Barrett in a non-title match and Ryback defeated United States Champion Rusev by countout in a non-title contest to advance while WWE Tag Team Champions The Usos were also confirmed for the 30-man bout.

The Usos will be pulling double duty as they will defend the Tag Team Championships against The Miz and Damien Sandow in the Royal Rumble's undercard. Miz and Sandow are also in the 30-man match and will work twice Sunday night as well.

The full field of Rumble participants includes Roman Reigns, Daniel Bryan, Rusev, Barrett, Bray Wyatt, Dean Ambrose, Kane, The Big Show, Goldust, Stardust, Justin Gabriel, Fandango, Fernando, Diego, The Miz, Sandow, R-Truth, Jimmy Uso, Jey Uso, Ziggler and Ryback.

This leaves nine slots open, which could be filled by announcements from the WWE or in the form of surprise entrants. The Dudley Boys, Randy Orton, Sheamus, NXT stars and Rey Mysterio are among the rumored names to return at the event.

Reigns has been the favorite to win the Rumble Match for the past few months, though Bryan's return may have changed up plans.

The winner of the Rumble Match will go on to face the WWE World Heavyweight Champion for the gold at WrestleMania 31 on March 29 at Levi's Stadium in California.

Another headlining bout on the Rumble card will see Brock Lesnar defend the WWE World Heavyweight Championship against John Cena and Seth Rollins in a Triple Threat Match.

The New Age Outlaws will also be on the card as they take on The Ascension while the Divas will have a tag team contest that will see Paige and Natalya take on the Bella Twins.

On the pre-show, The New Day will clash with Tyson Kidd, Cesaro and Adam Rose in a six-man elimination tag team match.
