Link: http://www.nflpa.org/Legal/ImportantDates.aspx (Prev ref by F. Fungi) "September 2, Saturday Roster cutdown to maximum of 53 players on Active/Inactive List by 4:00 pm EDT. Clubs may dress minimum of 42 and maximum of 45 players and third QB for each regular season and post-season game. " This is the 1st time I've seen a ref to a 42 player minimum; if a team had 12 players down with flu they'd have to dress them (or forfeit???). "September 8, Friday All clubs are required to identify their 49 player Active List by 7:00 pm EDT on this Friday and each Friday thereafter for a regular season Sunday game. No later than one hour and 30 minutes prior to kickoff, clubs must identify their 45 player Active List and third QB, if any." Never heard of the 49 player declaration before; thought the 8 inactives were announced 1.5 hrs before game.
