Leeds have started legal action to test the Football League’s collective television rights deal.
The Elland Road club have had 11 of their Championship games moved for broadcaster Sky and Leeds want to negotiate their own contract.
The Football League’s current TV deal is worth £100m-a-year. The other 71 clubs unanimously oppose Leeds’ stance.
Meanwhile, the Football League has taken out an injunction to force Leeds to play Monday’s game at Middlesbrough.
A Football League statement in January said that it regretted the late change of the date from Saturday, 13 to Monday, 15 February but added a legal challenge from Leeds had delayed the fixture announcement.
It will be Leeds’ 10th live televised league game of the season and United have also had their game at Brighton moved from Saturday, 27 to Monday, 29 February for the same reason.
Leeds chairman Massimo Cellino initially refused Sky entry for their home game against Derby on 29 December, although the club eventually allowed the broadcaster access.
Leeds United have been contacted about this story but have not commented.
The Football League has declined to comment for legal reasons.
