Rising had finished tied with Louisville City FC on points and wins, but Rising finished with a higher goal differential. However, just before the Western Conference Final, Phoenix Rising announced it would not host the Championship Final if it advanced that far. Rising was only in contention to host the final after San Diego Loyal walked off the field during its September 30 match in protest of Junior Flemmings directing a homophobic slur at one of its players. Due to the ensuing outcry, Rising announced that if it advanced to the Championship Final, it would give up home field advantage to the Eastern Conference champion.

During a game with San Diego Loyal on September 30, Junior Flemmings was accused of using a Jamaican homophobic slur against the openly gay Loyal midfielder Collin Martin. The Loyal, who had been leading 3–1 up to that point, walked off the field in protest and forfeited the match.

Video capturing an exchange between Rising coach Rick Schantz and Loyal coach Landon Donovan over the incident led to claims of Schantz telling Donovan that the incident was "part of the game," that the players were "competing," as well as accusations that Schantz tried to downplay the incident. Brandon McCarthy, a minority-owner, was accused of questioning the veracity of accusations made against Flemmings, suggesting in a direct message with another Twitter user that the Loyal, who forfeited a match against the LA Galaxy II in the days prior over the alleged use of a racial slur against a Black Loyal player, planned to forfeit the match to continue making a statement on social justice.

Prior to the incident, the Rising, along with McCarthy, were noted for their support of the LGBTQ+ community.

As a result of the incident and statements in the aftermath, both Flemmings and Head Coach Rick Schantz were suspended and fined. Schantz was reinstated as head coach on October 21 after Collin Martin accepted an apology by Schantz for his remarks.
