The cut-to-18 deadline, and #QFL Europe rule designations, must be made in two weeks by Thursday, October 2 prior to the week 5 Vikings at Green Bay game. Trade deadline is November 20 this year.
Rule 23 Section 1 Article 2
Prior to the Week 5 game: rosters must be reduced to 18 active players by Thursday, 11:59 P.M.
As this rule was passed prior to the advent of Thursday night games it is common law to make cuts prior to the start of game.
