Tiger Woods had the worst two seasons of his PGA Tour career over the past two years due to issues with his back. The 14-time major winner underwent two back surgeries in September and October and it's unknown when he'll make his 2015-2016 PGA Tour debut.

However, in his end of the year column, Woods touched upon his health, his career moving forward and the game of golf. Perhaps he'll be ready to get back on the course soon despite many speculating a prolonged absence (and even retirement).

"As far as 2015, it was a tough year physically and took a toll on my body. I had to battle through a swing pattern change and get that organized, because it was awful at the beginning of the year. I didn't play for the longest time because I was stuck.  

"The frustrating part was not being able to build on it throughout the year."

Woods was limited to just seven events in 2014 and 12 events in 2015. He earned just $556,873 over those two seasons with 2014 being the worst of his 20-year career. He also took a hiatus from the game last February because he said his play was not up to PGA Tour standards.

"The thing I'm looking forward to the most about 2016 is getting back out there again. I've missed it, and I would like to do it pain-free. I haven't done that in what seems like a long time. I've had it in spurts the last few years and have done some pretty good things, but I'd like to have sustained health. 

"Hopefully, I'll be able to play my way onto the Ryder Cup Team."

Although he's still unsure when his debut will come this year due to the lack of a timetable for his latest recovery from back surgery, the soon-to-be 40-year-old is optimistic about his future.

"Where do I see myself in the next five to 10 years? I am still playing golf at the highest level and winning tournaments and major championships."

Woods is dealing with a nerve issue in his back and while his medical team expects a full recovery, it's unknown when he'll be able to begin swinging a golf club again. The former No. 1 golfer in the world rushed back from injuries in the past and he noted earlier this year in an interview with Time Magazine that he is going to be prudent this time around to ensure he's fully healthy before he begins playing competitively again.

Woods should be back on the course this year at some point as he hopes to chase Jack Nicklaus' PGA Tour record of 18 career major championships. It might be a while from now, but he's taking the proper precautions to maintain longevity.
