The longtime KNBR host shared the news Friday, saying he is stepping away from broadcasting to focus on treatment. He did not disclose the type of cancer.

In a significant blow to the sports media landscape in the Bay Area, Greg Papa has announced that he has been diagnosed with cancer.

The 49ers posted a statement on social media shortly after the announcement on KNBR: “The 49ers family extends our unwavering love and support to Greg Papa and his family following his recent cancer diagnosis. We wish him a speedy recovery and look forward to welcoming him back to the radio booth as the ‘voice of the 49ers’ whenever he is ready.”
