Former Swansea player Oli McBurnie has been warned by the Football Association after he allegedly made obscene gestures to Cardiff fans at the south Wales derby.
McBurnie was spotted in the crowd supporting his former team at the game on Sunday.
The Swansea versus Cardiff game took place in the capital city and ended in a 0-0 draw.
Sheffield United striker Oli McBurnie has been warned of his responsibilities following the game on Sunday after the FA were made aware of images on social media involving McBurnie.
Television pundit Gary Neville had defended McBurnie on social media, saying it would be "a disgrace" were he to be charged.
McBurnie scored 26 goals in 62 appearances for Swansea before joining Sheffield United.
The reported £20 million transfer made McBurnie the most expensive signing in Blades history.
The 23-year-old was also pictured among Swansea fans in August when the Welsh club won 3-1 at QPR in the Sky Bet Championship.
