The FA launched an inquiry on Monday into Crystal Palace goalkeeper Wayne Hennessey's apparent Nazi salute on a team night out.
The Wales No 1 appeared to make the controversial gesture in a photo posted on social media by German team-mate Max Meyer.
Other members of the Palace squad can be seen in the shot, taken at a dinner on Saturday night after the FA Cup third-round victory at home to Grimsby.
Meyer posted the picture on an Instagram story, which disappear after 24 hours.
Hennessey, 31, denied on Monday he was making a Nazi salute, insisting he was merely waving and shouting at the picture-taker.
