Merthyr Town Football Club is investigating an allegation of racism following a league match on Monday.
The club, which plays in the seventh tier of the English pyramid, said it had been made aware of an alleged incident at Penydarren Park.
Hungerford Town accused a “section of the home crowd” of racially abusing defender Ramarni Medford-Smith during the Southern League Premier South game.
Merthyr said it “strongly condemns” such behaviour.
Hungerford manager Danny Robinson said in an emotional post-match interview: “Football is irrelevant today after what my player went through with a certain section of the crowd here.
“To be racially abused in 2024 is absolutely unforgivable and something needs to drastically happen.
“I should have been stronger because I don’t think we should have come out for the second half. I wouldn’t have blamed him [Medford-Smith] for storming off but we were in constant dialogue with him and he wanted to play on.
“It has marred a wonderful performance by a top side.”
The Martyrs won the game 3-0 to move back into the play-offs.
But the club said in a statement released after the match that it was working with match officials and Hungerford Town to deal with the alleged incident “as swiftly as possible” and would consider a lifetime ban against anyone found guilty.
It read: “Investigations into the incident are ongoing. However, as a community club, Merthyr Town FC strongly condemns the use of racist, abusive or homophobia language of any description: be that from a regular or casual supporter; at home or away.
“Such behaviour will simply not be tolerated, and appropriate action taken against any individual identified – including a lifetime ban from the club, in addition to any legal proceedings that may be instigated.”
The Football Association of Wales and South Wales Police have been approached for comment.
