Colin Montgomerie has decided to forgo any practice for the Volvo PGA Championship at Wentworth this week in order to rest his back.

A spasm almost forced Montgomerie to pull out of the final round of the Deutsche Bank Open on Monday, when he lost to Tiger Woods in a play-off.

And he will not risk aggravating the problem before Thursday's opening round at Wentworth as he chases his fourth Volvo PGA victory in five years.

Montgomerie, 38, has not won a tournament since the Scandinavian Masters last August.

But his second place in Heidelberg earned him �187,000 and lifted him 10 places up the European rankings to sixth.

It was the third time in succession he had led a tournament and he held his advantage right up until the 13th hole of the final round.
