Tiger Woods and Jason Dufner sure know how to put on their best poker faces.

Following the tabloid fiasco that unfolded earlier this month, in which Woods was accused of cheating on then-girlfriend Lindsey Vonn with Dufner’s former wife Amanda, the duo hit the greens at St. Andrews on Sunday for a practice round ahead of the British Open.

While Woods and Dufner seemed civil as they strolled the links and swung away on the fairway, we’re sure the small talk was kept to a minimum.

Dufner has yet to comment on the National Enquirer’s report, whereas Woods’ agent Mark Steinberg adamantly denied the story, telling Page Six via email: “This is 100 percent false. Absolutely zero truth to the rumor.”
