Swansea City forward Jamal Lowe was racially abused on Instagram following their defeat at Birmingham City on Friday night.
Lowe posted the offensive message on his Instagram page, writing "some serious idiots out there" alongside it.
Facebook told BBC Sport Wales the account which posted the message has been removed for breaking its rules.
Lowe is the third Swansea player since February to be subjected to racist abuse on social media.
After both those incidents, Swansea urged social media companies to do more to prevent online abuse.
The Championship club say they are "once again saddened and appalled" following the Lowe abuse.
"This is the third time in space of seven weeks where one of our players has been subjected to such abhorrent messages, and we continue to call on social media companies to go above and beyond to eradicate this appalling level of behaviour from their platforms," a Swansea spokesperson said.
"Jamal has the full and unwavering support of everyone at the football club."
Facebook, which owns Instagram, said it was "committed to doing more" after Cabango - as well as international team-mate Rabbi Matondo - was abused following Wales' 1-0 win over Mexico on 27 March.
After being alerted to the abuse sent to Lowe, Facebook said it does not allow attacks on people based on protected characteristics including race, religion, nationality or sexual orientation.
Former schoolteacher Lowe, 26, has scored nine goals in 41 Swansea appearances since joining the Welsh club from Wigan in August 2020.
He was playing non-league football before being spotted by Portsmouth in 2017.
