Striker Sergiu Bus has completed his move to Wednesday from CSKA Sofia.
The 22-year-old Romanian joins on a three and a half year contract for an undisclosed fee, although some reports have quoted a transfer value of £375,000.
He will wear the number 28 shirt and joins subject to international clearance.
However, Stuart Gray says Bus has not played a competitive game since the winter break in Bulgaria in mid-December and, although he has been training with CSKA, Wednesday fans might have to wait a little while to see him in action as he regains match fitness.
