The list of people who care deeply about the weeknight programming schedule on Comcast SportsNet is probably fairly limited. On the other hand, the overlap between that group and my core readership is probably fairly substantial. Thus, a few programming updates.

* On Sept. 3, the long-running “SportsTalk Live” weeknight talk show will be renamed “SportsTalk Live with Brian Mitchell,” and will have a new format. Instead of a rotating cast of two hosts who both offer commentary, Nicole Darin will be the regular co-host — reporting the news — while Mitchell will handle commentary and analysis.

* That show will add a daily interview with a newsmaker or athlete; the first two guests will be Bryant McKinnie and Katie Ledecky. The show will now begin with an opening commentary from Mitchell, and will end with a Doghouse segment.

* A new show, “Geico SportsNet Central: Football Tonight,” will also debut on Sept. 3. That show will air weekdays at 6 and midnight. This means that by Sept. 10 — when Redskins Nation and the daily Ravens shows debut — CSN will have 90 straight minutes of football programming each weekday, from 5-6:30. If that time slot sounds familiar, you might recall that the dearly departed Washington Post Live once ran from 5-6:30 weekdays on Comcast SportsNet.

* Mitchell’s show will move from 10:30 to 10, with an encore at 12:30. The signature SportsNet Central news show will move from 10 to 10:30. That show previously aired at 6; it’s been replaced by the Football Tonight show. SportsNet Central will continue to air at 1 a.m.
