Stoke City have announced that they have launched an internal investigation into an incident within the dressing room.

Recent reports had claimed that striker Kenwyne Jones was the target of a prank when he found a pig's head in his locker at the Clayton Wood training ground.

A statement on the club's official website said: "The club takes seriously reports of an incident at our training ground this afternoon. A full internal investigation will be carried out and those responsible for any unacceptable behaviour will be dealt with in accordance with the club's disciplinary procedures."

It is believed that a number of squad members were left feeling angry following the alleged prank.
