Oxford United have signed Australia Under-20 striker Matthew Fletcher on a short-term deal.
The 19-year-old was previously on the books of Premier League side Sunderland but left the club in July.
He told the club website: "I can't wait to start and hopefully make a good impression on the manager."
U's boss Chris Wilder added: "Matt is a player with bags of potential and a great pedigree. This is a great opportunity for him."
