Following reports that the 76ers had ended trade talks with Morey, the guard called him a liar.

Before talks broke down, Harden, 33, was reportedly keen to join the LA Clippers.

According to the NBA, the fine was for saying “he would not perform the services required by his player contract unless traded”.

“We respectfully disagree with the league’s decision to discipline James Harden for recent comments he made, which we believe did not violate the rule against public trade demands,” said the NBAPA in response.

“We intend to file a grievance and have our Arbitrator hear the matter.”

Harden was fined for comments he made on 14 and 17 August when he in effect threatened to strike by refusing to play for the 76ers over their refusal to trade him.

It was confirmed through the NBA’s investigation, which included an interview with Harden, that these comments referred to Harden’s belief that the 76ers would not accommodate his trade request.”

During a promotional event in China on 14 August, Harden made the controversial remarks about Morey.

In his words: “Daryl Morey is a liar, and I will never be a part of an organization he belongs to.” Let me repeat that: Daryl Morey is a liar, and I will never be a part of an organization he belongs to.

In subsequent interviews, Harden said Morey had broken his promise to trade him quickly.

ESPN reports that talks between the 76ers and the Clippers broke down due to his current team’s demands that he return for training camp in September.

While Morey was general manager of the Houston Rockets, Harden was named the NBA’s most valuable player (MVP) in 2018.

In a trade that sent Ben Simmons to the Brooklyn Nets, Harden and Simmons’ relationship played a major part in Harden’s move to Philadelphia.

With Joel Embiid, Harden helped the 76ers reach last season’s Eastern Conference semi-finals, where they lost to rivals Boston Celtics after blowing a 3-2 lead.

The 76ers play the Celtics in their first preseason game on October 8 before the regular season begins on October 24.
