QPR have completed the signing of Polish striker Adam Czerkas on a one-year loan.
Rangers have agreed a deal to sign the player permanently from Kolporter Korona at the end of the season.
Czerkas, who recently turned 22, is expected to feature in a pre-season friendly against Stevenage Borough on Wednesday night.
QPR boss Gary Waddock has been keen to sign a striker and is also interested in Southampton's Dexter Blackstock.
Rangers have had a busy summer and have already signed defender Damion Stewart and midfielders Armel, Nick Ward and Egutu Oliseh.
