Huddersfield have launched an investigation into reports of homophobic abuse during Saturday's home defeat to Brighton.
The Huddersfield Town LGBT supporters group, Proud Terriers, have claimed homophobic chanting was aimed at Brighton's travelling fans during the Terriers' defeat.
The West Yorkshire club have said any fans found to have been involved in the abuse will be banned from the John Smith's Stadium.
"The club is aware of reports of homophobic abuse at (Saturday's) game against Brighton," Huddersfield said in a statement.
"This is not something that Huddersfield Town will allow or accept. It is totally abhorrent and an affront to the overwhelming majority of the club's fantastic supporters.
"Officials at the club will do all they can to identify any individuals involved, who will face banning orders if proven.
"Huddersfield Town is extremely proud of its reputation as an inclusive club and the behaviour of a few individuals will not be allowed to tarnish this."
Brighton has one of the largest LGBT communities in the country and the south-coast club are understood to be aware of the reports.
The Seagulls secured their second Premier League away win of the season after a 2-1 victory.
