Boro were paired with Grazer AK from Austria in the draw earlier today. The game will take place on February 16th or 17th.
The return game will be played on Thursday 24th February.
The Austrian team's stadium only holds just over 15,000, so it looks there will not be many tickets available for Boro fans.
The winners of the tie will face either Feyenoord or Sporting Lisbon in the next round.
