Lyndon Dykes and Lee Wallace will be assessed ahead of QPR’s game against Blackpool.
Dykes missed Saturday’s draw with Hull after picking up a knock and is hoping to return for Wednesday night’s home match.
Wallace has been out with a groin problem but is also hoping to return to the squad.
With Sam McCallum also out, Wallace’s absence left manager Mark Warburton shot of options on the left flank.
He deployed Chris Willock there against Hull prior to Moses Odubajo coming on as a second-half substitute.
Odubajo set up QPR’s goal in the 1-1 draw, crossing for Ilias Chair to score the equaliser, and is expected to start against Blackpool.
McCallum, meanwhile, 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’ goal.
