The men were arrested by Nottinghamshire Police at the match between Mansfield Town and Notts County at Field Mill, in Mansfield, on Saturday April 16.
All three appeared at Mansfield Magistrates’ Court on Thursday 5 May 5.
Lewis Betts, 24, of Wheatacre Road, Nottingham was given a football banning order preventing him from attending any football ground in the country for three years for possessing a flare at the ground.
He was issued with a community order and ordered to pay costs of £85 and a victim surcharge of £60.
Charles Henry Barnaby, 33, of Nelson Street, Ilkeston, was also banned for three years, fined £120, and ordered to pay costs of £85 and a victim surcharge of £30, for running on to the pitch.
Matthew Woodward, 25, of Walnut Tree Gardens, was fined £130, and ordered to pay costs of £85 and a victim surcharge of £30 for being drunk and disorderly in the ground. He was not banned.
Chief Superintendent Mark Holland, of Nottinghamshire Police said: “The incidents that were witnessed at Field Mill last month were totally unacceptable and it is absolutely right that these three people should be brought before the courts and, in the case of two of them, banned from attending any football ground for a significant period of time.
“Law-abiding fans, including children, were left very distressed and frightened by the events of that day and it is important that they should know that Nottinghamshire Police takes a very serious view of incidents like this and we won’t hesitate to seek a prosecution if we have clear evidence of criminal behaviour in Nottinghamshire’s football grounds.”
