S-F Radio: NFL 49ers Name Broadcast Team

The San Francisco 49ers have introduced a new team of radio broadcasters to temporarily replace Greg Papa, the iconic Voice of the 49ers, as he prioritizes his health. The group, consisting of Guy Haberman, Justin Allegri, Troy Clardy, Carlos Ramirez, and Jack Smith, will serve as play-by-play announcers alongside color analyst Tim Ryan for the season.

Guy Haberman takes on the primary fill-in role while continuing as a Big Ten Network play-by-play commentator. With over a decade of experience, Haberman has worked with Pac-12 Network, FOX Sports, NBC/Peacock, NBC Sports Bay Area, and 95.7 The Game.

Justin Allegri brings 13 years of Bay Area football broadcasting experience, currently serving as the voice of Cal Golden Bears football and basketball. He previously covered San José State University sports for 11 years, has been a San Jose Giants radio voice since 2015, and contributed to MLB The Show since 2014.
