'Breakfast Club' co-host Frank Lewis out at WOGL

Breakfast Club co-host Frank Lewis is no longer with 98.1 WOGL, according to sources. Lewis join joins former co-hosts Bill Zimpfer and Valerie Knight in departing from the station over the last year.

WOGL could not be immediately reached for comment.

Lewis, a Beaver Falls, Pa., native who came to Philadelphia in 2000, confirmed his exit from the station Wednesday, saying he was "let go" Tuesday after 15 years there. Lewis also wrote in a post on social media that his time at the station was "a helluva run and a lot of fun." Accompanying Lewis' message was a picture of a pint of Guinness, playing on the host's well-known love for all things Irish:

In addition to Lewis' message, WOGL has scrubbed Lewis' host biography page from its website, as well as removed his biography from the Breakfast Club page. Fans, meanwhile, have begun posting messages of support to Lewis' Facebook page:

Lewis' exit leaves Marilyn Russell as the lone host of Breakfast Club. Russell replaced Knight after she was let go from from her role last December.

Knight's exit was followed in April by the departure of former Breakfast Club co-host Zimpfer. Zimpfer cited a lowball contract offer as his reason for leaving the station.

Lewis' departure is yet another high-profile departure from WOGL in several weeks, with Rockin' Ron Cade and Cadillac Jack Seville both exiting this month. 92.5 WXTU evening host Jennifer Reed also reportedly left that station, which, like WOGL, is owned by CBS Radio.

The changes come amid a $4 billion merger between parent company CBS Radio and Entercom Communications Corp. The merger will reportedly result in the establishment of the second-largest radio group in the United States, with 244 stations. The group would be outranked only by iHeartMedia, which has more than 860 stations.
