The seemingly endless flow of top golf talent pulling out of the 2016 Rio Olympics has been well-documented here, but it was still a harsh blow for the United States and the sport in general when, late Friday, the No. 2-ranked golfer in the world announced that he would also be withdrawing his name for consideration from his country's national team.

Dustin Johnson, winner of back-to-back tournaments including his first career major in the 2016 U.S. Open, announced in a statement that he will not play for the United States in Brazil next month.

In a statement Johnson said quote - "As an athlete, I can think of no greater honor than representing the United States in the Olympic Games. However, after much careful consideration and discussion with both my family and my team, I have made the decision to withdraw from the 2016 Olympic Games."

Johnson has joined a list including Australia's Jason Day (No. 1) and Adam Scott (No. 8), Northern Ireland's Rory McIlroy (No. 3), South Africa's Branden Grace (No. 11) and Louis Oosthuizen (No. 14), and Japan's Hideki Matsuyama (No. 17). There is also an expectation that America's Jordan Spieth (No. 3) will eventually withdraw from the Olympics as he recently hedged that he is seriously considering whether playing is worth the risk.
