The Argentinian, who joined Rangers in 2009, is currently sidelined with his second cruciate injury in two years.
Loftus Road manager Harry Redknapp recently suggested Faurlin may struggle to recover fully.
But Faurlin responded to those comments on Twitter, saying: "This make me feel even more determined and motivated than ever!!
"I will be back, I do still have plenty of years to play my football!! My rehab it's been perfectly on course."
