Sam McCallum played the full 90 minutes for QPR’s B team in a behind-closed-doors friendly against Oxford United on Tuesday afternoon.
The on-loan Norwich youngster, 21, had surgery after suffering a badly torn hamstring in October.
He has recently featured twice for Rangers’ Under-23 side.
McCallum could potentially return to the first-team squad for Saturday’s game against promotion rivals Blackburn.
He has started just eight league matches for the R’s but impressed before suffering his injury.
Oxford won the game 3-1. Faysal Bettache scored QPR’s goal.
