The Football Association has released a statement condemning anti-social behaviour from supporters after several incidents this week, including one involving a Nottingham Forest fan.
A Forest season ticket holder has been jailed for 24 weeks after pleading guilty to a post-match assault on Sheffield United striker Billy Sharp at the City Ground on Tuesday. There has also been trouble at Port Vale, and Everton vs. Crystal Palace in recent days, with the FA now looking to clamp down on such behaviour.
The FA reinforced that it is illegal to enter the playing area, and sent a message to all clubs that they are responsible for stopping such incidents from occurring in the first place.
