Bill Cosby is replacing lawyers on his legal team as he looks to appeal his conviction and three-to-10-year sentence in his Pennsylvania sex assault case, according to an the Associated Press report.

A Friday court filing said the 81-year-old comedian is replacing Joseph Green, a Philadelphia lawyer who handled his September sentencing, with criminal defense attorneys Brian Perry and Kristen Weisenberger.

Cosby was found guilty in April of drugging and sexually assaulting a woman more than 30 years his junior.

Another lawyer, Peter Goldberger, worked with Green on a motion last week challenging the outcome of the case — the first step toward an appeal.

Cosby has switched more than a dozen lawyers from his case, according to the AP, including Tom Mesereau, who once represented Michael Jackson in his 2005 child molestation trial.

Cosby is also facing a lawsuit from his former lawyer Samuel Silver, of the firm Schnader Harrison Segal & Lewis, over an alleged $280,000 in unpaid bills.
