The annually released edition of the magazine features athletes in nude and semi-nude photographs and showcases their physiques. A photo gallery for the 2019 issue will be available online Sept. 4 with the magazine debuting Sept. 6. This is the final year of print publication for the issue, which will move to a digital-only format moving forward.
"I was at a position in my life where I felt this was something I wanted to do," Yelich told reporters Monday. "I was not really worried about the whole being naked thing."
Koepka first posted a preview photo from the magazine shoot last week.
