Spanos told local reporters was "a lot of crap" and that he planned to remain in L.A. for the long haul.
The Athletic originally reported "through NFL sources that the possibility of the Chargers moving to London has been broached among league personnel.
"The Athletic also has learned that, while the team is fully committed to Los Angeles where it will move into the new $4.5 billion stadium with the Rams next year, the Chargers would at least listen if the NFL approached them about London as a possible option."
The story says NFL owners would support a move to London if the Chargers, the less popular of the two NFL teams in the city, want to relocate. The report included a quote from Spanos, who says the team is committed to Los Angeles.
After the Athletic story was published, Spanos reiterated that message to local media in no uncertain terms, including to beat writer Jason B. Hirschhorn:
WARNING - EXPLICIT LANGUAGE:
The Chargers team account posted a popular clip from the movie "Wolf of Wall Street," in which the character Jordan Belfort, played by Leonardo DiCaprio, declares "I'm not leaving ... The show goes on":
The NFL has long focused on making in-roads in Europe, and has been holding at least one game in London since the 2007 season.
The Jacksonville Jaguars, a team owned by billionaire businessman Shahid "Shad" Khan, who already owns a soccer club in London, are often floated as a contender to move. The Jaguars have played a home game in London each of the last seven years.
The Chargers played a game in London once in 2008 and again in 2018.
