Kick It Out says that hate is alive and well within football.
Ivan Toney and Rico Henry made accusations after the victory.
It came hours after two fans were arrested for making gestures during a game.
The Metropolitan Police said the men were ejected from the section of the stadium because they were suspected of being involved in a racially-aggravated public order offence.
Kick It Out's head of player engagement Troy Townsend said that they have been made aware of a number of new alleged anti-Semitic and racist comments and gestures linked to several clubs over the weekend.
We can't comment on the specifics of cases while investigations are ongoing. The events of the weekend highlight the fact that hate is still alive in football.
We commend the energy that was put into addressing these incidents. We hope that appropriate and decisive action is taken against those involved.
There were 206 hate crime incidents reported in stadiums in the first half of the 2021-22 season, compared to 146 in the same period in the previous year.
