Jason Dufner has revealed his happiness ahead of his return to competitive golf at the Perth International this week.

The American has been out of action for almost three months due to neck and shoulder problems, but he believes that he is likely to feel the benefits of having more time to improve areas of his game.

"It has been about 11 weeks since I last played so it is getting better," Dufner told the European Tour's website. "It was frustrating to miss the last major, the play-offs and Ryder Cup but in the end it was probably nice to do it.

"It was nice to get my fitness and health better and I worked on one of my weaknesses which was my putting.

"I've had a couple of weeks with no pain swinging the golf club and they have told me I can't do more damage."

Dufner is looking for his first win since the 2013 US PGA Championship this week.
