Hearts Under-20 coach Jon Daly has added 18-year-old Polish goalkeeper Wojciech Gajda to his squad.
The youngster joins on an amateur contract from the American club New York Red Bulls. He will sign professional terms when the January transfer window opens.
As Gajda arrives, Robbie Buchanan is moving out. The 20-year-old forward has joined League One Brechin City on an emergency loan deal until December 24.
