However, as TNA's financial troubles grew, he left the company after competing in his last match, which took place in January 2014, and moved to New Japan Pro-Wrestling before eventually joining WWE. Just when it looked like he would never step foot in a TNA Wrestling ring again, that all changed tonight.A few days ago, TNA released a huge teaser about Styles making an appearance at Slammiversary.
