West Ham United have revealed that the Football Association have made contact with Ravel Morrison regarding a homophobic threat he posted on Twitter.

The 19-year-old, who was responding to an accusation that he was a drug user, could now face a fine or suspension for his actions.

"West Ham United are aware that the FA have written to Ravel Morrison asking for his observations regarding comments on Twitter," read a statement on the club's official website.

"Ravel and the club will co-operate fully with the FA's request and have until Monday evening to respond.

"There will be no further comment from West Ham United or Ravel at this stage."

Morrison joined the Hammers from Manchester United on transfer deadline day.
