He hasn't been seen in competitive golf since August last year, but Tiger Woods is once again the subject of intense speculation at the Masters.

Rumours are abound Woods may make a shock appearance at Augusta, with some American media claiming he's a chance of playing the tournament next week.

It's all been fuelled by a Golf Channel report quoting Woods' agent Mark Steinberg who says there's no update on his recovery from a back injury.

Unlike PGA Tour events, the only deadline for the Masters is to register at the tournament office before their first-round tee time.
