Leeds United have condemned a homophobic chant aimed at Crystal Palace midfielder Conor Gallagher when the teams played on Tuesday.
The incident took place during the Premier League's Rainbow Laces campaign to support LGBTQ+ inclusion.
The Elland Road side won the game 1-0 following a late Raphinha penalty.
"We are aware of a homophobic chant directed at a Crystal Palace player and we want to be very clear that this is unacceptable," said a Leeds statement.
"We will continue to work closely with Marching Out Together (Leeds United's LGBT+ supporters' group) and all of our supporter groups to ensure that we do everything within our power to eradicate homophobia and any other form of discrimination from our football club.
