Blues have not had the pleasure of the Surrey-based official taking charge of any of their games either this season or last season whilst the same applies to Rangers.
In total Paul Melin has refereed in 4 league games so far this season in which he has handed out 14 yellow cards and no reds.
Mr I Bentley and Mr G Evetts will be Paul Melin's assistants for the game at Loftus Road on Tuesday night.
