Melbourne Storm full-back Billy Slater is confident his NRL career is not over despite undergoing season-ending surgery this week.

Slater's campaign lasted just one game after the State of Origin star once again injured his troublesome left shoulder against St George Illawarra Dragons on March 7.

The 32-year-old Queenslander, who went under the knife on Tuesday, had already undergone a shoulder reconstruction in June last year and was limited to just seven appearances in 2015.

However, Slater has vowed to return next season.

"The day's going to come when I have to hang up the boots, I just don't feel that day is right now," Slater told Channel Nine. "I feel I can get this shoulder injury under control and that's why I've taken the steps to fix it right now.

"Not only do I not want to end my career like this, I want to have a healthy life after football as well."

Slater added: "It's never easy to take, especially after you've had it repaired previously and it was pretty tough to swallow, but there was bad news and there was good news.

"The bad news obviously was that they had to go back in and repair my shoulder again.

"The good news was the surgery went really well and the surgeon is very confident that I'll make a full recovery."
