(Reuters) - Former world number one Jason Day is cautiously optimistic his back problems will not flair up and hamper his challenge at this week's Players Championship in Florida.
The Australian, the 2016 Players champion, made it through only six holes at the Arnold Palmer Invitational last Thursday before back issues forced him to withdraw in pain.
