WWE SmackDown heads to the Paycom Center in Oklahoma City, Oklahoma tonight, airing live on the USA Network from 8 p.m. ET with several major matches and appearances already confirmed.

One of the biggest attractions of the evening will be the first SmackDown appearance of newly crowned WWE Champion CM Punk. After capturing the championship from Sami Zayn on this past Monday's episode of Raw, Punk is set to address the blue brand for the first time with the title around his waist.

The tag team division will also take center stage with championship gold on the line. WWE Tag Team Champions R-Truth and Damian Priest will meet AAA World Tag Team Champions The Viking Raiders in a Winner Take All showdown, with both sets of titles at stake.

Elsewhere on the card, Finn Balor goes one on one with Tama Tonga in a clash that carries Bullet Club history, while former NXT rivals Trick Williams and Carmelo Hayes renew their rivalry in singles competition.
