Donald Sterling isn't going away quietly.

SI.com says the Clippers owner has threatened to sue the league and claimed, through a lawyer, that he will not pay a $2.5 million fine.  

Sterling was also banned for life from the NBA after tapes of racial comments surfaced.  

The 80-year-old Sterling recently said in an interview with CNN's Anderson Cooper that he "is not a racist" and "made a terrible, terrible mistake."  

The league has made Dick Parsons interim CEO of the Clippers.
