Chelsea fans plan a protest against Sky TV during Thursday's Premiership clash with Everton.
Both Everton and Chelsea are unhappy, the London club saying it undermines "the sporting integrity of the competition".
But any demonstration leaves Everton with a dilemma over whether to allow a banner that embarrasses Premier League paymasters Sky Sports, or to try to stop the protest, which could lead to accusations of being heavy handed and anti free-speech.
