The word on 'Daily News Live'

Comcast SportsNet is promising a big announcement on Tuesday's edition of its Daily News Live show.

Sources describe this scenario:

DNL -- a programming staple since October 1997 -- will be shaved from 90 minutes to 60 minutes, so it will run from 5 to 6 p.m.

Moving up a half-hour, to 6 p.m., will be SportsNite.

Following at 6:30 will be pregame shows for that night's games.

My sources did not say when the change is effective (most likely in time for Flyers season), or what will be shown on the nights when there are no games.
