Green went into the game under huge pressure after the taunts of Leeds United's Paddy Kenny.
Hughes said: "Rob didn’t sulk at all.
"He’s been great in training and you saw that in the game, the saves he pulled off. He’s done well. We were tight at the back and the goalkeeper made some fantastic saves."
After the game, the QPR owner Tony Fernandes tweeted: "Pleased for Rob Green."
