[1] With supporter groups running with the catchphrase, "Bury Us With The Cup",[2][3] the Loyal would qualify for the USL Playoffs as the 3rd seed in the Western Conference, and played in what would end up being their final match in the Western Conference Quarterfinals on October 22 at Torero Stadium, in a 4–3 loss in extra time to Phoenix Rising FC.

[5] As a member of the USL Championship, the San Diego Loyal entered the U.S. Open Cup in the second round on April 5, matched up against third division club Albion San Diego, a member of the National Independent Soccer Association.

[11][12][13] On August 24, 2023, owner Andrew Vassilanis released a statement that he would shut down the team,[14] and the USL announced that it would transfer the franchise rights of the Loyal due to an inability to find a "viable near- and long-term stadium solution", with the 2023 season set to be the club's last.

[15] The team had searched for a venue to replace Torero Stadium but were unable to find suitable facilities in San Diego County; a plan to relocate to Santa Barbara was also considered, but negotiations failed to produce a solution.
