PFA chairman Clarke Carlisle has called for stricter penalties for players found guilty of using foul and abusive language on the pitch.
Chelsea captain John Terry was acquitted of racially abusing QPR defender Anton Ferdinand this week, but the evidence given demonstrated the frequent use of offensive language on the pitch.
And Carlisle, who was released by Burnley in May, says football governing bodies must take action in order to prevent further examples.
"I don't agree it should be that way [that abusive language is common on the field]," he told BBC Sport. "If players were sent off and banned because of the language, it would cause them to address their behaviour.
"It would cause the clubs to clamp down on it too. In order to change it, it would take a very strong line from the referees, a very strong line from the governing bodies and it would probably cause mayhem for the short-term period."
According to FIFA rules, the use of "offensive, insulting or abusive language and/or gestures" should result in a red card, and Carlisle has urged referees to follow the guidelines.
"We do have the regulations within the game to stamp out any kind of foul and abusive language but they are just not enforced to the nth degree," he added.
