LOUISVILLE, Ky. (WDRB) -- PGA Tour standout and Louisville-area native Justin Thomas on Saturday apologized immediately after microphones caught him muttering a homophobic slur upon missing a putt during the third round of the Sentry Tournament of Champions in Hawaii.

Thomas missed the 4-foot par putt, and a microphone caught him using the slur.

"There’s just no excuse. I’m an adult; I’m a grown man," Thomas told the Golf Channel after his round. "There’s absolutely no reason for me to say anything like that. It’s terrible. I’m extremely embarrassed. It’s not who I am. It’s not the kind of person that I am. But it’s — unfortunately, I did it and I have to own up to it and I’m very apologetic.

"Like I said, it’s in excusable. I’m speechless. ... It’s bad. There’s no other way to put it. I need to do better. I need to be better. It’s definitely a learning experience. I deeply apologize to anyone and everybody who I offended and I’ll be better because of it."

Thomas isn't the first to find himself apologizing for such a remark recently. Former Cincinnati Reds announcer Thom Brennaman was suspended from his job with the Reds and Fox Sports Ohio and later resigned after uttering the same word during a broadcast this past season. 

The PGA later issued a statement on the matter: "As he expressed after his round, we agree that Justin’s comment was unacceptable." The organization is expected to fine Thomas, according to the Associated Press, though it does not disclose fines publicly.

Thomas is the defending champion at the event, and is 4 shots back heading into play Sunday.
