(CNN) -- Less than a year before it stages the World Cup, Brazil is once again in the news for the wrong reasons.
Brazilian football players protested Wednesday and said they could take more action -- possibly "drastic measures" -- if their confederation doesn't make changes to the country's overcrowded calendar.
They want, among other things, more vacation time, longer preseasons, fewer games and a bigger voice in decision making.
In some matches, the players crossed their arms before the opening whistle. In others they did so after the whistle blew.
And in some instances, they passed the ball from one end of the field to the other after the referees threatened to give players yellow cards.
Also in a game, players from both sides unfurled a banner in the middle of the pitch while the national anthem played. It read: "For a football that is better for everyone."
In a statement, Common Sense F.C. -- not a club but a movement symbolizing the changes the players want -- said on its Facebook page: "If there are attempts to prevent players from expressing themselves in a peaceful way, drastic measures will be taken.
"We expect an official position followed by moves that will benefit Brazilian football."
According to Brazilian media, the future measures could include players crossing their arms for a longer period of time, wearing red clown noses or even halting a game.
There was no official reaction on Friday, which is a national holiday in Brazil.
The protests came two weeks after a former professional football player was found decapitated in Rio de Janeiro.
