West Ham winger Jarrod Bowen has been warned by the Football Association over a tweet from 2012 that contained a racist term.
Bowen apologised for the content of the post earlier in April, describing it as "offensive and immature".
The FA took into account Bowen's age at the time, as well as the fact that the post was made eight years ago.
Bowen was not registered as a participant in football or as playing affiliated football when he sent the tweet.
He would not have been under FA jurisdiction at the time.
West Ham also spoke to Bowen and said the issue would be "dealt with internally".
