Ralph Barbieri filed suit today against KNBR and its owner, Cumulus Media, claiming he was wrongfully fired as a sports talk host because of his age (he’s 66) and because he suffers from Parkinson’s disease and Type 2 diabetes. The suit seeks $10 million in damages, the Chronicle reports. Angela Alioto, one of his attorneys, said he was told by management that he was fired because he came to work late and wasn’t properly preparing for his show. He joined KNBR in 1984 and co-hosted the afternoon drive show since 1996.
