Dallas Mavericks fans outraged by Doncic's trade continued calling on the team to fire general manager Nico Harrison. As the Mavericks hosted the Sacramento Kings Monday night, fans at the American Airlines Center were holding signs that read "fire Nico."

Mavs fan Jacob Posner posted a GoFundMe campaign to raise money for billboards outside American Airlines Center in Dallas to protest general manager Nico Harrison and the Mavericks' owners, the Adelson family. As of Friday morning, the campaign had amassed nearly $42,000, with the top contributor having donated $1,000.
