Blackpool's Grant Ward was the target of racial abuse following the Tangerines win over Sunderland last night.
The 26-year-old posted a screenshot of a private message sent to his Instagram account, which read “b****** monkey”.
The abuse was sent to Ward at 9pm last night, just minutes after the final whistle had blown at the Stadium of Light.
The Seasiders have released a statement condemning the abuse and have confirmed that police are investigating the incident.
The statement read: "Blackpool Football Club is appalled by the abhorrent, racist abuse received by Grant Ward following the team’s fixture at Sunderland last night.
"The contents of the message, on his Instagram account, have since been reported to the social media platform and are now being investigated by the police.
"Grant has the Club’s full and unwavering support in this matter, as we continue to collectively take a stand in the fight against racism and online hatred.
"Enough is enough."
Sunderland also released a statement condemning the abuse.
They tweeted: "We utterly condemn the vile abuse directed at Grant Ward following our match against Blackpool.
"We will work closely with the police and football authorities to ensure those responsible are identified and punished for this abhorrent and unacceptable behaviour. Enough is enough."
The abuse comes just days before clubs across the country are set to refrain from posting content on their social media channels in an attempt to stamp out racism, discrimination and abuse online.
Sunderland head coach Lee Johnson called for social media companies to implement verification protocols when setting up accounts so that people can be held accountable for their actions online.
When asked about this weekend's social media blackout, Johnson said: "That could be an hour long conversation. I think it's something, but I don't think it's going to change a lot if I'm honest.
"It's a consideration and an effort that's really important to try and stop some of this.
"It's never going to stop until people are accountable for what they put on via verification like passports or verification of something like that.
"We know social media companies aren't going to change it because they use it every fake profile and alias as a consideration to their end game advertising goal.
"I can't see it changing so I think that the more bots we can use to figure out if there's any sort of discrimination or deep attack on any individual, it's probably the short term-solution to success and making people feel a bit better about themselves on social media."
