This is what the Minecraft wiki has to say:

''Navigate to the Minecraft server directory, open the world folder, open the player's folder, and delete the .dat file which has the UUID that corresponds to the player's current username. This folder is at "minecraft\world\players", where "minecraft" is the folder where Minecraft was installed on the server. This will cause the player to start over at the spawn point with no inventory. The player's changes to the world will be untouched, along with any inventory stored in chests. This will not ban the player that has been deleted.''
