The Scotland international made a 13,000-mile round-trip to play a friendly against Japan last weekend but is now fully-focused on the trip to Loftus Road.
"The lads are right up for it from what I've experienced in training this week, we're determined to get a good result and stay up there in the table," he told the Lancashire Evening Post.
"QPR are a very good side and they obviously have a bit of cash to splash when you consider who owns the club. But that doesn't always guarantee success in football.
"We are an organised side with some good players going forward.
"If we can keep our shape right and defend well, we are confident of going there and getting a decent result."
