The rumour mill is going into overdrive as news that Tiger Woods is working on his golf game with coach Hank Haney this week hits Golf Digest and the Golf Channel.

Unnamed sources state on both golfing medias' websites say that Woods is practicing as hard as he ever has done.

There is speculation that he could play at Augusta National, where he has won the Masters four times.

If he is on form, he could even return as early as March 25 to defend his title at the Arnold Palmer Invitational in Orlando.

US PGA players Charles Howell and JB Holmes told the Golf Channel they have seen Woods practising his swing at Isleworth and it's looking good.
