The two-time major winner may follow Rory McIlroy, Jason Day and Shane Lowry in withdrawing his name for consideration
Jordan Spieth admits he is unsure whether or not he will take part in this summer's Olympics in Rio.
The two-time major winner becomes the latest in a spate of withdrawals, with a number of players including Jason Day, Rory McIlroy and Shane Lowry all removing their names from consideration for the Games.
While the trio cited concern for the Zika virus as their reason for not wanting to represent their country, Spieth assessed his workload when answering if he would take part.
"Right now, I'm uncertain," the 22-year-old told reporters ahead of tomorrow'a WGC-Bridgestone Invitational.
"Do I feel an added burden? Potentially. I think all four of the Americans do. I feel like one of four with maybe a slightly higher burden now that the guys have dropped out.
"I've always been excited about the possibility but there's quite a few different factors that would turn somebody away from going.
"I have not received enough information to make an informed decision either way or not so as we gather more information I will be able to make a decision one way or the other. When I feel confident, I will make a decision either side."

The Games falls during a busy schedule in the golf calendar, with the Open exactly a month before the event gets underway and the PGA Championship just two weeks beforehand.
"I've heard some stories on both sides about the security threats that Brazil and Rio have," Spieth added.
"Transportation is a big security issue down there, how to get from one place to another with the different kind of violence that we don't see here. I'm going to get answers soon on how we plan to be secured down there.
"This is personal safety type and future planning-type decision which is going to outweigh any pressure that we feel [to compete]. Let's not put me on save the Olympics. The Olympics are going to be fine."
