The San Francisco 49ers announce a rotating team of radio broadcasters who will fill in for legendary Bay Area sports announcer Greg Papa while he focuses on his health. Papa announced on August 1 that he would be stepping away from his duties at KNBR and the 49ers to focus on his cancer treatment and work toward a full recovery.
Guy Haberman, Justin Allegri, Troy Clardy, Carlos Ramirez, and Jack Smith will each serve as play-by-play commentators alongside veteran color analyst Tim Ryan for the 2025 season.
Haberman will act as the official radio broadcast’s primary fill-in anchor in addition to his ongoing play-by-play work with the Big Ten Network. Entering his first season with the 49ers, Haberman brings more than a decade of experience across Pac-12 Network, FOX Sports, NBC/Peacock, NBC Sports Bay Area, and 95.7 The Game.
Joining Haberman in the booth, Justin Allegri comes with 13 years of experience calling Bay Area football games. In 2023, Allegri became the voice of Cal Golden Bears football and men’s basketball, building on an 11-year tenure as lead play-by-play broadcaster at his alma mater, San José State University. He has also served as a radio voice for the San Jose Giants since 2015 and contributed to MLB The Show broadcasts since 2014.
Troy Clardy, familiar to local college football fans as the voice of Stanford Cardinal football and men’s basketball since 2023, brings extensive national experience, including three seasons calling NCAA football on Westwood One. Clardy also covered the 2024 NCAA Women’s Basketball Tournament and has called NFL games on Compass Media Networks, notably Christian McCaffrey’s first 49ers start in 2022.
Carlos Ramirez, a long-standing Bay Area media personality, will contribute his 23 years of television, radio, and digital experience. Ramirez currently hosts 49ers Pre- and Postgame Live on NBC Sports Bay Area and covers the Giants and A’s. He has called NFL, NBA, MLB, MLS, international soccer, and Olympic events in both English and Spanish and previously contributed to the 49ers Spanish Radio Network from 2019 to 2021.
Rounding out the team, Jack Smith, a San Jose native and 2025 Jim Nantz Award winner for outstanding collegiate sports broadcasting, recently graduated from the University of Southern California. This year, Smith has worked as Media Relations Assistant and radio voice for the Fredericksburg Nationals, Single-A affiliate of the Washington Nationals.
Papa and Ryan collectively have over a decade of experience on the 49ers radio broadcast. Papa, a Bay Area broadcasting icon, has over 30 years of experience, earning three California Sportscaster of the Year awards and induction into the Bay Area Radio Hall of Fame in 2018. Ryan, a former NFL player, is nationally recognized for his work with Westwood One Radio, NFL on FOX, and SiriusXM NFL Radio.
The 49ers’ rotating broadcast team marks a significant effort to maintain the franchise’s storied radio legacy while supporting Papa’s ongoing health journey.

Big mistake by the 49ers. First, we don’t need five different play-by-play guys. I listened to Guy Haberman during preseason and he’s good. They should just use him.
Secondly, using Carlos Ramirez is a big joke. He was terrible on Giants pregame shows, which is probably why they dumped him. And I think the amount of times he will move in and out of speaking with a Spanish accent will become very unnerving for those listening to the game.
