Blackpool manager Lee Clark has asked for help in tracking down striker Nile Ranger, with the player not turning up for training for two weeks.
Clark says the 23-year-old ex-Newcastle striker "appears to be back in London".
But he told the Blackpool Gazette: "If anyone can let us know where he is, send me a letter and we will go from there."
Ranger tweeted: "I'm in London. Family issues. For the people that claim they don't know where I am."
Clark added: "I don't know where he is. I haven't seen him for more than two weeks.
"He's been asked to report into training and has been asked to play in games and he hasn't been seen."
Ranger was sacked by his previous two clubs for a breach of discipline.
Ranger, who joined Blackpool in the summer after being released by Swindon, has scored two goals in nine matches this season.
