Footballers "are not going to take this abuse any more", says Crystal Palace winger Andros Townsend.
The boycott, which aims to tackle abuse and discrimination, runs from 15:00 BST on 30 April until 23:59 on 3 May.
"We're starting to fight back," Townsend told BBC Sport. "I'm proud of the players. We're finally finding our voices and speaking up as a community."
The 29-year-old England international said: "Hopefully it'll let the major media companies know that we're not going to take this abuse any more.
"Do I think a three- or four-day blackout will make a difference?
