An important member of the San Francisco 49ers organization is making a comeback. Greg Papa, the team’s radio announcer, will return to the booth for the final two regular season games, he announced on KNBR Wednesday morning. Papa has been battling leukemia since July. The 63-year-old is in remission. He’ll make his season debut on Dec. 28, a Sunday Night Football matchup against the Chicago Bears. Here's the moment Greg Papa was officially activated by 49ers Director of Broadcast Partnerships Bob Sargent. Papa is BACK❤️💛 https://t.co/9zvZaq4GjG pic.twitter.com/WxLB4KyYua— KNBR (@KNBR) December 17, 2025 ...read more read less
