Dallas Mavericks general manager Nico Harrison has been subject to death threats and racist remarks following the team’s trade of Luka Dončić to the Los Angeles Lakers last Saturday.

ESPN’s Tim MacMahon reported the news on Friday’s edition of NBA Today.

“This is a heartbroken fanbase, and there have been some very unfortunate developments regarding that anger,” MacMahon began.

“Nico Harrison has been subjected to death threats. There have been racial epithets included in some of those. Certainly, security’s going to be beefed up. There will be protests outside the arena early. Those are planned. Security will absolutely be beefed up. Nico Harrison is not going to be in his normal seat in the stands. There’s no reason to subject him to that kind of a security risk.

“So that has been definitely an unfortunate part of this whole storyline. Obviously, the fans’ anger—hey, they have every right to feel like they got a generational superstar ripped away from them—but clearly, lines have been crossed.”

The Mavericks have been on the road for three games since the trade, but Saturday will mark the team’s first home contest in the post-Dončić era when Dallas hosts the Houston Rockets at 3 p.m. ET.

MacMahon’s report occurred one day after TNT Sports sideline reporter Allie LaForce issued these remarks during a break in the action amid Dallas’ 127-120 road win over the Boston Celtics.

“One big concern though is the safety of the players, the front office, going back to Dallas,” LaForce said. “We hope fans make the wise decision and remember that this is a game and lives are far more important.”

LaForce led into those words by noting that Mavs head coach Jason Kidd believes big man Anthony Davis, the primary piece heading to Dallas in the Dončić trade, had the shoulders to “carry this load.”

Obviously, the death threats and racial slurs are terrible, heinous and completely inexcusable ordeals for Harrison (or anyone) to deal with.

Fans are clearly hurt after the 25-year-old Dončić, a five-time All-NBA first-team player who just led the Mavs to the NBA Finals, was sent to L.A. in one of the most shocking sports trades in history. But clearly, some have taken this entirely too far, to the point where Harrison’s safety now needs much more focused attention on Saturday.
