WEEI is reportedly set to replace one of their longest-serving sports talk hosts with a host from their rock music sister station.

In the wake of Gerry Callahan’s announcement that he’d hosted his last show on WEEI, parent company Entercom announced that WAAF’s Greg Hill will move to the sports talk station to host “The Greg Hill Morning Show.”

According to the station’s announcement, the show will air 6:00 a.m. EST to 10:00 a.m. EST starting July 29. Mike Mutnansky, who co-hosted the “Mut & Callahan” show, will move back to hosting evening programming at WEEI.

With the “Hill-Man Morning Show” jumping stations, Entercom also announced a number of moves at WAAF. Longtime Hill-Man personality Lyndon Byers will stay at WAAF in a new capacity. Meanwhile, producer Mike Hsu will move to WAAF’s afternoon drive slot.

In the meantime, Entercom announced WAAF’s “morning drive will shift to a music focus during the national search for Hill’s replacement.”

Hill will continue WEEI’s weekly interviews with New England Patriots quarterback Tom Brady as part of “Patriots Monday.” Additionally, WEEI announced that Hill will also have monthly interviews with Governor Charlie Baker.

“I am thrilled to embark on the next chapter in my career in Boston. WEEI is a legendary Boston station and one of the country’s first sports stations,” Hill said in a statement. “I am excited to anchor mornings moving forward. I also want to thank WAAF and all of the listeners and co-workers who have made the last 28 years so amazing. The good news is I will still be talking to them every weekday, just down the dial at 93.7 FM.”

As Boston Radio Watch pointed out on Twitter, WEEI set precedent of such a crossover when Hill recorded a show with WEEI host Christian Fauria before Super Bowl LIII in Atlanta.

WEEI and WAAF are both owned by Entercom and both operate out of the same facility in Brighton. Hill currently serves as the host of WAAF’s “Hill-Man” morning show, but has long engaged in a fair amount of sports talk as part of its programing. Hill joined WAAF in 1986 served as the face of the “Hill-Man” morning show for more 28 years.

Callahan leaves WEEI after a 20-year run to station, rising to become one of the most prominent sports talk personalities.
