"The French federation has made public that a procedure, that could go up to termination has been initiated against Gilbert Ysern," the FFT said in a statement.
French sports daily L'Equipe had earlier reported that Ysern, who is also the director of the French Open, had been sacked by federation president Jean Gachassin.
"It's very brutal," Ysern was quoted as saying by L'Equipe. "I'm a bother but I have done nothing wrong," he added without elaborating.

The newspaper said that Ysern and Gachassin had been at odds since the president sacked Davis Cup captain Arnaud Clement last year and replaced him with former French Open champion Yannick Noah.
The FFT statement added that Jeremy Botton had been appointed director general on a caretaker basis "until the end of the procedure".
