Tiger admits swing changes may be necessary

Tiger Woods has conceded he may be forced to make changes to the way he swings in order to maintain a healthy back following surgery.

The world no.1 has been sidelined since undergoing microdiscectomy surgery for a pinched nerve in his back at the tail end of last month which has left him unsure when he will be ready for a full return to action.

Some reports suggest that Woods will be back on the greens in around four months, although Tiger has yet to confirm any such claim. However, the American has now revealed he may have to tweak his golf swing in order to protect his back in the future.

"I made the decision to have surgery because physically I just couldn't make a golf swing. That pretty much sums it up," he said.

"Once I begin swinging a club again, I'm not sure if I will have to make any changes to protect my back.

"We have to make sure my back heals fine and I have the strength and mobility going forward."
