Perry Ng early injury prognosis:
A particularly worrying sign for Cardiff was that one of their star players, Perry Ng, was taken off at half-time after taking an injury to his leg.
The defender went down a couple of times in the first half, with one stoppage just before the break lasting about four minutes as he received treatment from the City medical team.
With Mahlon Romeo a doubt for the weekend, too, Cardiff will be sweating on the fitness of Ng, who filled in at right-back at Loftus Road.
"He gets a knock. We will have to see how that settles," Hudson said of Ng. "Sparky [Mark Harris] gets a bit of a knock. We tried to use the squad as much as we could with the subs that we made throughout the game.
"We will have to recover right and go to Sunday with full heart. Perry was a whack. He went for a challenge and got caught. I can't give any information on that now. It's so fresh so it might have swollen a bit, but we'll see what we can do going towards the game on Sunday."
