Concerns over spectators' safety has led to the crowd capacity at Mansfield Town's Field Mill ground being cut by half for next season.
Field Mill's capacity has been reduced from 9,368
Nottinghamshire County Council took the decision which means the maximum number of fans at matches there will be 4,684.
The council said the cut was due to a poor standard of stewarding and a lack of a pro-active approach to safety.
A number of fans ran onto the pitch after the Stags' final home game when they beat Barnet to avoid relegation.
Some supporters complained to the club about "heavy-handed stewarding" after they were allegedly manhandled.
The county council is responsible for setting the ground capacity.
Sue Storey from the authority's emergency planning team said: "We've had concerns for some time.
"We've been giving the club the opportunity to develop stewarding and they introduced a new training regime for stewards at the start of the season.
"Unfortunately what we saw on Saturday was not really a demonstration of good-quality stewarding."
She said the council would monitor the club's performance over a number of matches next season.
"This reduction affects all ends, so the stand which takes the away supporters will also have a 50% reduction. That will bring it down to about 955 which will have an effect for some of the local clubs who may want to visit."
The average crowd for the club's League Two games this season has been 3,176.
The biggest crowds were 6,646 for the Carling Cup tie against Portsmouth, 6,182 for the local derby against Notts County and 4,837 for Doncaster in the FA Cup.
No one from the club has been available for comment.
