CBS Radio recently announced that bestselling author and Washington Post sports columnist John Feinstein would host a show on the soon-to-launch CBS Sports Radio Network.

Also, Feinstein is being used as a holiday-time fill-in on local CBS sports-talker 106.7 The Fan.

Which led some to wonder whether Feinstein could become a regular addition to The Fan’s lineup. The answer? No.

“John is ramping up for the launch of his new show on CBS’s new national sports radio network,” program director Chris Kinard explained in an e-mail. “Since he’s in the CBS family and already a regular guest on The Fan, it’s a great opportunity for us to have a quality host help us with vacation fill-in, and a great opportunity for John to get ready for the launch of his new, national show.”

Feinstein will be hosting shows for The Fan this Wednesday from noon-2, next Wednesday and Thursday from noon-2, and next Friday from 10-noon. Then it’s on to the national format.

The Fan, meanwhile, will begin using CBS Sports Network content to replace its current Fox Sports Radio programming on Jan 2. This will not mean the elimination of any current local shows; the new network will air whenever Fox Sports Radio has previously aired, typically overnights and during early mornings on weekends.

CBS Sports Radio will also air 24/7 on 106.7’s HD2 channel.
