Dallas Mavericks general manager Nico Harrison has been fired after a Tuesday morning meeting with team governor Patrick Dumont, sources told ESPN.
Assistant general managers Michael Finley and Matt Riccardi are being promoted to lead the Mavs' basketball operations department on an interim basis, sources added.
Dumont intends to address his reasoning for the decision in a letter to the team's fans Tuesday, a source said.
Harrison has been under fire from Mavericks fans since he stunningly traded Luka Doncic to the Los Angeles Lakers on Feb. 2, months removed from the then-25-year-old five-time first-team All-NBA selection leading the franchise to an NBA Finals appearance.
