It seems we have a pretty good idea of what AJ Styles will be doing later tonight at TNA Slammiversary. Thursday night, in the closing moments of TNA iMPACT, the company revealed its worst-kept secret this week: WWE Superstar The Phenomenal AJ Styles would be appearing this Sunday at Slammiversary.

Styles, 48, was a fixture of the company for more than a decade, wrestling under the TNA banner from 2002-14. He's widely considered to be one of the all-time greats of TNA, thanks to his numerous accomplishments, including five world title wins.
