Two Bradford Sunday Alliance soccer teams face being booted out of the league.
The management committee have written to clubs to vote on whether the unnamed sides should be allowed to continue next season.
The League is refusing to name the clubs until after tonight's meeting.
League chairman Adrian Grimshaw said a series of violent incidents on the pitch had led to calls for their exclusion.
"There are two clubs on the agenda for this evening's meeting," he said.
"We have excluded clubs in the past but it was some time ago.
"The situation is that there comes a time when you have to say 'no more'.
"Anything that happens untoward tends to be reported on quite a large scale in newspapers so we have to take steps to see that this doesn't happen.
"It's our job to ensure that the football we administer is played in a fair as possible way.
"There are always going to be flashpoint situations in a physical game but when you get violence of the nature that we have seen this season then we have to take a stand and say no.
"We won't stand for it and it is then up to the member clubs to take a vote as to whether they want those clubs to continue."
All clubs in the Sunday Alliance have been contacted about the situation which is to be discussed at the League meeting. The clubs will take part in a secret vote.
Grimshaw added: "We would never ever take this action for one incident because there are occasional
flashpoints between the mildest of teams.
"It happens at a professional level when players should be a damn sight more disciplined - and they are on £70,000 a week.
"It has to be an accumulative thing for us to take action like this."
