A complaint was lodged following the Bucks’ home National League North fixture against Chester on Boxing Day, the only occasions supporters were permitted for a match in the recently-curtailed season.
It was alleged a small group of supporters made inappropriate comments towards a female Chester physio during the match.
The FA contacted Telford and, upon reviewing evidence, issued a formal warning.
When asked for a response, the club told the Shropshire Star: “AFC Telford United do not tolerate any type of inappropriate behaviour and we will continue alongside our stewards to work against discrimination in football.”
The clash finished 2-1 to the visitors. Telford were 14th before the season was voted null and void by a majority of clubs.
