FIFA President Gianni Infantino has ruled out showing blue cards to players who are sent to the sin bins.
A plan has been drawn up by some football lawmakers to have a new card join the old red and yellow cards that referees can post.
the The proposal surfaced last monthwith Sky News learning that some protocols have already been prepared for release.
Sin boxes are currently only used at the lower levels of grassroots football, where players are sent to them for 10 minutes for dissent.
But Mr Infantino rejected the idea of using blue cards in the professional game.
Speaking in Scotland, ahead of Saturday's meeting of the International Football Association Board (IFAB) in Loch Lomond, he said: “FIFA is completely against blue cards.
“Red card versus blue card. Impossible. You have to be serious.”
“We are always open at IFAB and at FIFA to consider ideas and proposals, but once you have considered them, you also have to protect the game, the essence of the game, the traditions of the game.
“No blue card.”

The world governing body has four of the eight votes on the FIFA Council, which holds its 138th annual meeting this weekend. The other votes are held by the four British countries.
Infantino also rejected calls for temporary concussion replacements, following a request from players' unions concerned about long-term brain damage caused by head injuries.
FIFA prefers that teams make additional permanent substitutions to replace players suspected of sustaining concussion.

Mr. Infantino said: “We've studied it and medical experts say it's simply impossible in a few minutes to be able to determine whether there's a concussion, whether a concussion is serious or not.
“For this reason, if a concussion is suspected, a player must be substituted.
“If you want to take care of the player's health, players go out and another player comes in, and that's the end of it.
“This would protect the player. All that's left is not protecting the players' heads, just making some PR announcements.”
A group of former players in the United Kingdom have sued the International Federation of Association Football Associations (IFAB), which makes football's laws, alleging that they suffered brain injuries due to playing football, and that the authorities failed to take reasonable measures to protect them from repeated concussive and near-concussive blows. .

A spokesman for the Professional Footballers' Association told Sky News: “It sends a terrible message about the priorities of the game when the International Football Association Board takes seriously the idea of removing a player for 10 minutes for dissent, but opposes it if the player suffers concussion.” . .
“Leagues and federations agree that temporary concussion substitutions are a positive step for player well-being.
He added: “As the maker of the rules of the game, the FIFA Council must reflect this by allowing trials to take place, not standing in their way.”
Last year I found a Swedish study Football players are 50% more likely to develop dementia From the rest of the population.
But goalkeepers – who rarely head the ball – had no increased risk of developing Alzheimer's disease or dementia.
The study concluded that this “supports the hypothesis that mild head impacts that occur when heading the ball can explain the increased risk in field players.”
