Dallas Mavs eject fans protesting Luka Doncic trade

DALLAS - Some Dallas Mavericks fans angered by the trade of superstar Luka Dončić were removed from the American Airlines Center on Monday night.

Mavs fans thrown out of AAC

What Happened:

Multiple Dallas Mavericks fans were removed from the AAC during the team's loss against the Sacramento Kings.

Mavs PR tells FOX 4 that there were two incidents that led to fans being removed from the game.

The team says in the first incident, the guest brought in a sign that broke a rule in the NBA Code of Conduct banning signs with explicit language, profanity or a derogatory characterization of any person.

Photos from the game show the fans holding signs that say "Fire Nico," referring to Mavericks General Manager Nico Harrison.

Social media videos show one of the fans mouthing "Fire Nico" on the Jumbotron during karaoke.

Mark Cuban confrontation

What they're saying:

Fan Chris Taylor tells FOX 4 he started to chant, "Fire Nico" while the Mavs were shooting free throws. 

The chant caught the attention of Mark Cuban, who was sitting about 20 rows in front of Taylor. He says Cuban told him to sit down.

"And when he did that, I pointed back at him and said, ‘You sit down! You did this! This is your fault!’ Yelling at the top of my lungs," said Taylor.

Taylor started filming once he was told by security to leave. At first, he refused. But once Dallas police got involved, Taylor got up.

The other side:

In an email to FOX 4, Cuban says that the fans were booing while the Mavericks were shooting free throws late in the game.

Cuban says he turned around, and the fan became confrontational.

"He started screaming at me. I had no idea what he said, but he was obviously mad. He couldn't hear anything I said, but it was clear what I was saying," Cuban wrote to FOX 4. "I didn't care what he was saying. He was saying it the whole game. I cared that fans were booing him while we had the ball in crunch time or were shooting FTs. The time when they should be silent or cheering for the Mavs. That was it."

Mavs fan ‘clowns’ owner Miriam Adelson

What we know:

FOX 4 cameras caught Taylor and his friend, Garrett Bussey, as they exited the arena. Bussey was wearing a t-shirt with Mavs owner Miriam Adelson depicted as a clown.

In Taylor's incident, the Mavs say Bussey was wearing a t-shirt that broke the code of conduct and that they were "intoxicated, disruptive and uncooperative."

Bussey and Taylor say they were not intoxicated.

"I have not used foul language one time," said Taylor. "We were there as fans cheering the Mavs on to win the game. But at the same time, I am going to voice my opinion for what else is happening."

Patrick Dumont booed at AAC

The Dallas Mavericks fans also expressed their frustration with team governor Patrick Dumont.

Dumont received loud boos as he walked back to his second for the second half of the game.

Dumont angered fans with recent comments to the Dallas Morning News.

In the comments, the Mavs' governor seemingly took a shot at Dončić's conditioning.

"Jordan. Bird. Magic. Kobe. Shaq. They worked really hard every day with a singular focus to win. And if you don't have that, then it doesn't work. And if you don't have that, you shouldn't be part of the Mavericks. If you want to take a vacation, don't do it with us," he said.

Mavs All-Star Kyrie Irving talked about the emotion from the crowd after the game.

What they're saying:

"I think it has graduated from, just like, hate to anger. It's the cycle of emotions. You know, the hate, the anger, the grieving and then the passion. You have to give credit to Dallas fans. They've really cheered, not only for Luka, but for the Mavericks for 40 some odd years and this is their community team. It's just like I felt when the New Jersey Nets moved to Brooklyn. I'm not comparing it, but I felt a way when I was a kid, even when J-Kidd was on the Nets and he got traded, I was mad at J-Kidd for a while as a young fan. It's just part of human nature and this journey in the NBA business and the NBA lifestyle and just the connectivity and engagement we have with the fans," Irving said.

NBA Fan Code of Conduct
