Jordan Spieth has become the latest star golfer to announce he won't take part in Rio 2016 as the sport prepares to return to the Olympic Games.

SOUNDBITE: (English) Peter Dawson, President, International Golf Federation:

(Announcing the players who have pulled out on deadline Monday)

"Now today is qualification day when the Olympic golf rankings determine the 60 men and 60 women who will be eligible to be entered for the Olympic competition by their respective national Olympic committees. The details of who has qualified have just been published. Sadly we've been advised today that Victor Dubuisson, K.T. Kim, and Jordan Spieth are not available to play".

SOUNDBITE: (English) Ty Votaw, Vice-President, International Golf Federation:

(On Spieth's reason for pull-out)

"He called us earlier today just before this press conference, and he's going to be addressing his reasons for choosing not to participate tomorrow in his press conference. But in the phone call, it was out of concern for the health issues that we've been talking about."

SOUNDBITE: (English) Peter Dawson, President, International Golf Federation:

"Speaking collectively though, there is no doubt that the number of withdrawals hasn't shed golf in the best light. Hasn't shown golf in the best light, and we have to accept that. But we do understand why these individual decisions have been taken. Personally, I think there's been something of an overreaction to the Zika situation, but that's for individuals to determine, and there's certainly a great deal of concern about this issue inside the game of golf, no doubt about that."
