KNBR talk show host Tom Tolbert will have a new partner Monday as Adam Copeland replaces the let-go Larry Krueger and Rod Brooks.

KNBR radio is shaking up its lineup again and on Friday pulled longtime talk-show hosts Larry Krueger and Rod Brooks off its airwaves.

Krueger and Brooks had teamed with Tom Tolbert in the 2 p.m. to 6 p.m. slot. Tolbert ran solo Friday and, according to a source at the station, will have a new partner Monday, Adam Copeland.

“Rod and Larry are no longer part of the show. It’s part of the business. It’s brutal. It stinks,” Tolbert said as he signed off Friday. “I’m going to miss those guys. I love both of them. They were both consummate professionals, both fun to be around, both with a great sense of humor, totally different with the way they did the show, but both were dedicated.”

Brooks previously partnered with Bob Fitzgerald in an earlier time slot before the station went in a new direction in 2019 with Fitzgerald departing. Krueger previously was a morning host as Gary Radnich’s sidekick.

Krueger and Brooks joined Tolbert about the time Greg Papa moved to the station from 95.7 FM in 2019.

“He’s a pro,” Tolbert said of Brooks. “You don’t last in this business for 20 years without being a pro and being really, really talented, and same with Larry. Larry did this a long, long time, and he just has a passion for sports. You know he watches all the games. They both do. But Larry watches them three or four times.”

In the end, the ratings weren’t up to par, and KNBR management responded with more changes.

“You just don’t know what’s going to work and what’s not going to work,” Tolbert said. “You work with a couple of really talented guys, and for whatever reason, it just didn’t. ... Some things click, and some things don’t.”

On Twitter, Krueger wrote, “Today was my last day” at KNBR. He expressed appreciation for several colleagues “and last but certainly not least, all the incredible listeners. Thank you all. More updates coming.”
