Bass, who is also head of communications, says in the statement that the NBA and WNBA want the basketball series to be respectful and inclusive workplaces for all employees.
"As soon as the investigation is complete, there can be talk of acting," Bass said in the statement.
Racist language can have fatal consequences for owners of the American basketball league.
In 2014, Los Angeles Clippers owner Donald Sterling was suspended for life and fined $ 2.5 million after a recording that revealed racist comments.
The NBA then forced a sale of the club.
Former and current employees testify in ESPN's article about Suns owner Sarver's racist language, that they felt like his property and that he created a destructive culture that coaches followed.
Sarver denies the allegations.
- I welcome the investigation that will clear my name, he says.
