Ohio court records showed Monday that York had been fined $1,150 after being hit with misdemeanor charges of disorderly conduct and possessing criminal tools.
Multiple US media reports said York was initially held on a charge of "engaging in prostitution" following his arrest by East Palestine Police on Sunday.
That charge was subsequently amended to misdemeanor disorderly conduct following his no contest plea.
York was also sentenced to one day in jail on each charge, but was released on Monday due to time served after being detained following his arrest.
A no contest plea is not an admission of guilt but an acceptance of a conviction and punishment, usually as part of a plea bargain.
York, 46, is the principal owner and chief executive of the San Francisco 49ers and is also a co-owner of English Premier League side Leeds United and Scottish giants Rangers.
