World No 1 Jason Day has responded to critics of golfers who have elected to skip the Rio de Janeiro Olympics.

Golf's return to the Olympics for the first time since 1904 has been soured by the withdrawals of a number of top men's players - many of whom have cited health concerns due to the outbreak of the Zika virus in Brazil.

Rio Games chief Carlos Nuzman told a media event in Rio over the weekend that top players had "tried to blame Zika, but the media have shown that they are not coming because there's no prize money."
