UEFA wants players who hurt an opponent to stay off the field until the injured party is ready to return.
Head of refereeing Pierluigi Collina said on Wednesday it was not fair for teams to gain a temporary one-player advantage by injuring an opponent.
"This is something that has gone on since (forever), I would say, but it's unfair," Collina said at a season-ending briefing.
"Football gives the advantage to the team of the player who committed a foul and is cautioned."
The Italian official, who refereed the 2002 World Cup final, insisted "something has to be considered".
Laws of football can be changed at annual meetings of the International Football Association Board, which comprises FIFA delegates and the four British football federations.
The panel has pledged to run more trials and pilot projects to test ideas.
UEFA President Michel Platini joined Collina to promote their five-referee system of match officiating used in UEFA competitions to rule on goal-line decisions and penalty box incidents.
Platini said most of his 54 European member countries now use five officials - placing an extra assistant beside each goal - in top-tier leagues or selected high-profile matches.
Italy, Belgium and Turkey are among the adopters.
Collina said he recently briefed analysts working for British broadcasters about how five officials worked together.
Three goal-line decisions were required from the Premier League's camera technology systems in 380 match this season, he said.
However, 4,093 corner kicks were also awarded in which goal-line technology could not assist the referee.
Collina cited an example from his own refereeing days when he should have disallowed a key goal by Chelsea captain John Terry which helped eliminate Barcelona from the Champions League in 2005.
Having an extra assistant watching the goalmouth would have told Collina that Terry's teammate Ricardo Carvalho illegally blocked Barcelona goalkeeper Victor Valdes, the former referee said.
Platini has acknowledged it was "becoming complicated" for some federations to adopt the system because of added costs training and employing more referees.
