Louis Oosthuizen has withdrawn from the Masters prior to his second round because of injury.
Oosthuizen was in the same group as Tiger Woods and shot an opening 76.
Augusta National Golf Club confirmed on Friday that the South African, who finished second in the 2012 Masters when he lost to Bubba Watson in a playoff, had withdrawn.
“Due to injury, Louis Oosthuizen has official withdrawn from the Masters Tournament prior to the start of his second round,” the statement said.
