Major WWE Superstar set for return on SmackDown - Reports

WWE is set to air tonight's live SmackDown from Madison Square Garden. The company often loads the card up when returning to The World's Most Famous Arena, and now sources have revealed spoiler details on a big segment set for tonight following weeks of rumors and speculation.

There has been tension within A-Town Down Under for weeks. WWE has teased a babyface turn for Austin Theory, but Grayson Waller has dismissed the talk while also fueling the speculation with heel antics. The current WWE Tag Team Champions have been feuding with DIY, which led to both teams on The Grayson Waller Effect on the June 14 episode, where a brawl broke out after DIY tried to get Theory to leave Waller.

Theory ended up saving his partner from a Gargano superkick by taking it himself as Ciampa dropped Waller. DIY then posed with the titles to end the segment, which came two weeks after Waller pulled his partner into a dive by Gargano, then used the distraction to pin Johnny Wrestling in singles action.

Waller and Kevin Owens lost a Money in the Bank qualifier to Andrade last week. Theory was not at ringside, and it was later reported that he was pulled from the show after waking up that morning with swelling in his face. Theory is set to return on tonight's SmackDown.

A new report from Fightful Select notes that a backstage segment is planned with A-Town Down Under on tonight's SmackDown. It remains to be seen if DIY will be involved, but the angle is scheduled to air as the final segment of the episode before the show-closer, which is The Bloodline's Acknowledgement Ceremony.

WWE has not confirmed when the DIY vs. A-Town Down Under title match will take place. The match is rumored for Money in the Bank on July 6.
