Tiger Woods has tumbled to No 49 on the latest World Rankings list but it looks as if he might just squeeze into his own Chevron World Challenge by the skin of his teeth.

That's because only the top 50 in the world are allowed to play in the end of season event which he has hosted since its inception several years ago and which is taking place from 1 - 4 December at a Thousand Oaks in California.

At the current rate he is plummeting down the Rankings list, the long-time former World No 1 would have had the red-faced task of asking for an invitation to his own tournament, but with the cut-off point for the event coming up tomorrow on Tuesday September 20, he'll only just make it - and with a huge sigh of relief both by himself and the organisers.

Woods, who was sidelined for several weeks earlier this year and saw his last hope of qualifying for US golf's end-of-season FedEx Cup play-offs fall away when he missed the cut at the final major of the year, the PGA Championship, has intimated that his next tournament will be the Frys.com Open at the start of October.

A few weeks back when Woods's chances of qualifying for the Chevron World Challenge were already looking questionable, its tournament director Greg McLaughlin said he was confident the 21st Century's richest sportsman would be in the top 50 when the time came, saying that the organisers hadn't considered taken any steps to ensure he gains entry, like for example throwing out the world ranking requirement.

"We haven't contemplated anything relative to that at all," he said. "We're confident he's going to be in the top 50 and will be eligible to play."

Phil Mickelson, who for a spell in recent seasons seemed to be the only man capable of reeling in Woods and taking over the Rankings crown, is also on the slide on the rankings table.

On Monday he had fell to No 9 and now sits behind Englishmen Luke Donald and Lee Westwood, Northern Ireland's Rory McIloy, Germany's Martin Kaymer, the leading Americans, Steve Stricker and Dustin Johnson, who are at Nos 5 and 6, Australian Jason Day and fellow American Matt Kuchar.

The week's big movers after the BMW Championship was winner Justin Rose who rocketed from 40th to a top 20 spot at No 17 and Geoff Ogilvy, whose third place at the same event saw him move from 50th to 39th and earned him a qualifying spot in the International team for the Presidents Cup.
