TNA Director of Authority Santino Marella has announced the main event for the Slammiversary pay-per-view, where the TNA World Champion, Trick Williams, will defend his title against two TNA stars in a triple threat match.

WWE’s Williams won the title at NXT’s Battleground PLE, becoming the first WWE star to hold a TNA title. Since his win, Williams has been feuding with Mike Santana and even successfully defended his title once against him. But their rivalry has continued, and Santana will get another shot at the title when he faces Williams as well as former TNA World Champion, Joe Hendry, at Slammiversary.

Marella made the announcement on social media, revealing that the decision was made after consulting with TNA management.
