The 39-year-old 14-time major champion, in the midst of the worst season of his career, missed the cut at last month's US Open at Chambers Bay with rounds of 80 and 76, the worst 36-hole effort of his career.
"I've made a little bit of progress. Obviously, that's not saying much," Woods said. "I'm looking forward to getting out there and competing."
Woods, the former world number one who has slumped to 220th in the rankings, makes his only tuneup for the British Open in two weeks at St. Andrews against a field whose only top-10 rival is third-ranked Bubba Watson, the two-time Masters champion coming off a PGA victory last week.
Mark Steinberg, the agent for Woods, told Fox News in an e-mail the report linking Woods to Boyd was "Absolutely 100 percent false," and a "Complete lie and fabrication," he told the Golf Channel the story was "categorically false" and a "ridiculous rumor."
He has not won a major title since the scandal erupted, ruining his good-guy clean cut image and as a result saw his endorsement deals suffer a major blow.
Speaking before the Boyd report circulated but after his practice rounds, Woods continued to back his swing changes and work with consultant Chris Como despite his ongoing struggles where even mediocrity would be an improvement.
"I know what I'm doing out here," Woods said. "I know what it feels like. I know where my game is and what progress I have or haven't made. That's what I'm concerned about."
Woods missed the cut in 2012 after going 71-69 for 36 holes the last time he played the Greenbrier, where scores typically finish well below par.
