Wilfried Zaha has been targeted with alleged racist abuse on Twitter, after Crystal Palace's 1-0 win over Newcastle at St James' Park.
Zaha won the penalty that resulted in Luka Milivojevic scoring the game's only goal and was allegedly tagged in posts containing racially abusive words on Twitter.
- Brentford fan arrested for 'racist abuse'
- Wigan condemn 'racist abuse' of Byrne
- Northampton players 'racially abused'
Sky Sports News has asked Crystal Palace for a comment.
Two other incidents of alleged racial abuse were reported by Championship clubs on Saturday.
A Brentford season ticket holder was arrested after Derby's Duane Holmes complained of racial abuse in the dugout at Griffin Park.
Wigan said they were angered by alleged online abuse directed at Nathan Byrne after he rescued a point for the Latics at Bristol City.
Former QPR manager Chris Ramsey gave his view on the apparent rise in racist abuse in football, speaking to Sky Sports News at the British Ethnic Diversity Sports Awards on Saturday evening.
"We're always disappointed, but it's never really gone away has it?," said Ramsey. "Now there is more awareness, which is something I think is important.
"People are aware that these incidents are more prevalent than not.
"So, fair play to the people that are dealing with it and fair play to the people that have brought it to our attention."
