Bill Cosby has ousted his high-powered defence team just months after his conviction of sexual assault.
Cosby's spokesman Andrew Wyatt said that Tom Mesereau and the rest of the retrial team have been replaced by a Philadelphia-area defence attorney with experience handling sex crimes cases.
The new lawyer, Joseph Green, did not immediately return a message.
Mr Wyatt would not say why the change was made.
Cosby is scheduled for sentencing on September 24 on three counts of aggravated indecent assault for drugging and assaulting a woman at his suburban Philadelphia mansion in 2004.
The charges will likely be combined into one charge that carries a standard sentence of five to 10 years in prison.
The 80-year-old comedian has been on house arrest since his conviction in April.
