A tweet containing a racist term which was posted by West Ham winger Jarrod Bowen in 2012 is being investigated by the Football Association.
"I wish to apologise unreservedly for the unacceptable content of that post, especially to all connected with West Ham United," said the 24-year-old.
The FA said it was "aware" of the tweet and "looking into" the circumstances.
Bowen, who began his professional career at Hereford as a 17-year-old, played for Hull City before joining West Ham in 2020.
"This is not an example I wish to set and it certainly does not portray the values and principles that I hold," said the Englishman.
