In October, while Alexa Bliss and Mickie James started a feud with WWE Hall of Famers Trish Stratus and Lita, Fox began teaming up with Jinder Mahal as they were announced as participants in the upcoming season 2 of Mixed Match Challenge. James and Bliss were supposed to face Stratus and Lita at WWE Evolution, the first ever all women's pay-per-view. However, just three days before the event, on October 25, it was announced that Bliss was pulled off the match due to a concussion she suffered beforehand and Fox will replace her, in which an emotional Fox claimed was the most important match of her entire career. At the event, Fox and James lost to Stratus and Lita after Stratus pinned James. In December, Fox and Jinder Mahal defeated Ember Moon and Curt Hawkins in the quarterfinals and Bayley and Apollo Crews in the semi-finals to qualify to the finals of the tournament. At the pay-per-view, Fox and Mahal lost to Carmella and R-Truth in the finals of the Mixed Match Challenge after Carmella submitted Fox. Throughout the rest of 2018, with Bliss out of in-ring competition, Fox was paired with Mickie James as the two continued to team up in various matches.
