Sutherland says his time at the League Two club is helping his development.
He said: "I'm really enjoying it. The lads have been brilliant with me and the manager is trying to play the right way, which is only going to benefit me.
"Every footballer is inspired to play games. I'm thankful I've got that opportunity here. My chances are limited at QPR because of the heavy investment so I was more than willing to come here to play in front of people and carry on progressing.
"Everyone at QPR has helped me out a lot with me being injured for the majority of last year. This is the right time to be out playing games."
