Longtime KNBR personality Ralph Barbieri has been let go, station operations manager and program director Lee Hammer told Chronicle Sports Editor Al Saracevic on Wednesday.

Hammer would only say Barbieri “is no longer with the station. It was a management decision.”

Hammer said Barbieri’s on-air partner, Tom Tolbert, would host their show, “The Razor and Mr. T,” by himself later Wednesday.

In October, Barbieri dropped the bombshell that he was suffering from Parkinson’s disease. The revelation came during contract negotiations with the station.

“My contract is expiring soon,” Barbieri said at the time, “and if I am to continue at KNBR, I’d like to start with all our cards on the table, face-up. I’ve gotten to know Lew Dickey (CEO of Cumulus Media, parent company of KNBR) a little bit, and my gut feeling was that he could deal with my situation at an honorable level, so I gave him a call and told him everything.

“He let me know that KNBR wants me back. He didn’t say on what terms, but the fact that he didn’t view the Parkinson’s as a red flag, that was a huge relief to me.”

Barbieri, 66, started working at KNBR in 1984.
