Owner Massimo Cellino has defended the club's decision to suspend assistant manager Steve Thompson.
Thompson was told ahead of Leeds' defeat to Blackburn on Saturday, with Neil Redfearn threatening to quit the club over the decision.
Redfearn was also reportedly told not to pick top scorer Mirco Antenucci.
Ten-goal Antenucci has clause in his contract that says he is entitled to another year should he net 12 times, and was left on the bench for Saturday's fixture.
Cellino, speaking from Miami, told the Sun: “I’m told Steve Thompson called our sporting director Nicola Salerno an offensive name in front of other people after the game at Fulham.
"This is unacceptable. The board backed Salerno and I understand this.”
