KNBR ends its relationship with longtime Bay Area sports broadcaster Greg Papa, the longtime lead play-by-play voice of the San Francisco 49ers. The station also dismisses Papa’s midday co-host, Greg Silver, as part of a programming shakeup that brings back veteran host John Lund.

The change comes while Papa is publicly described by outlets as battling health issues. Yahoo Sports reports that Cumulus Media, KNBR’s owner, says it cannot comment on the specifics of Papa’s departure, citing limitations on discussing details. A separate report characterizes the station’s response as cryptic, following Papa’s cancer diagnosis, and similarly focuses on the lack of explanation for why the broadcaster is let go.

Across the two accounts, the outlets agree on the dismissals and the midday schedule changes, while differing mainly in how they frame the station’s response—one emphasizing an inability to comment on specifics, the other highlighting the cryptic nature of the statement—rather than providing additional confirmed details about the decision.
