Adam Scott has revealed he could turn his back on the European Tour next season following proposals to tighten up membership rules.
The Australian currently has full membership for both the European and US PGA Tours and has already played a total of 22 events between the two this year.
However, under new plans it is likely European Tour members will have to compete at four out of six designated events next season which is likely to complicate the schedules of those playing on both sides of the Atlantic.
Scott, who has struggled for form all year, believes the European Tour are right to try and protect their tournaments and sponsors with the new measures, but claims it could force him to focus his efforts on just one tour in 2010.
"I believe it's becoming harder and harder to play multiple tours," Scott said ahead of this week's Australian Masters in Melbourne.
"My playing poorly this year doesn't help. But those years of Ernie Els running second in the US and winning the Order of Merit, I don't think you're going to see too much of that.
"I think Europe is doing the right thing (by tightening membership requirements). But if that's the case, and with where I am with my game, I'm going to have to focus on one or the other and give it 100 percent.
"Otherwise you run the risk of potentially not playing well on either tour. If you want to compete in the FedEx Cup, you've got to spot Phil Mickelson, Jim Furyk, Vijay Singh seven to 10 events. These are not exactly lightweights.
"With the depth of talent on both tours, it's going to be hard for me to play two tours next year.
"If you finish 20th on one and 15th on another, you don't know how good that is."
In a warning to the likes of Rory McIlroy who has confirmed his plans to play on both tours next year, Scott, in addition to his own, highlighted the cases of England's Ian Poulter and Justin Rose who he also felt were suffering by trying to play two tours.
