Justin Thomas says he'll go through an individual training programme to "become a better person" after being heard uttering a homophobic slur under his breath when he missed a putt at a tournament in Hawaii this month.
Clothing brand Ralph Lauren ended its long-time sponsorship with Thomas following the incident two weeks ago, which the World No.3 described as "humiliating and embarrassing and it's not me."
Thomas has spoken to his other sponsors and hopes they will stand by him as he looks to educate himself and restore his reputation.
"It's not a word I use," Thomas said on Wednesday, referring to the slur he blurted out when missing a five-foot par putt on the fourth hole of Sentry Tournament of Champions.
"But for some reason it was in there and that's what I'm trying to figure out – why it was in there.
"And like I said, it's going to be part of this process and training programme, whatever I need to do, not only to prove to myself but to prove to my sponsors and prove to the people who don't know who I am that that is indeed not the person I am."
Speaking from the Abu Dhabi Championship, where he will be playing this week in a rare appearance on the European Tour, Thomas said he was upset but respected Ralph Lauren's decision.
"I wasn't disappointed because I put them in a terrible position. I was just more upset. I had a great relationship with a lot of people there." – Justin Thomas
"They just felt like they needed to move on so that's exactly what I'm doing as well," Thomas said.
"I wasn't disappointed because I put them in a terrible position. I was just more upset. I had a great relationship with a lot of people there and we had the opportunity to do it all together."
Pushed on the training programme he intends to follow, Thomas said he would be keeping it "at a personal level."
The Abu Dhabi Championship starts Thursday and is Thomas' first event since the incident in Kapalua.
He will be playing in the tournament for the first time in what will be only his fourth start in a regular European Tour event.
Rory McIlroy will play in the same group as Thomas for the first two rounds at Abu Dhabi Golf Club, and does not expect the issue to affect the American's game
"He maybe won't be as ignorant to offend people – obviously what he said was offensive to a large portion of the population," McIlroy said.
"He'll be better for it, he'll learn, he'll move on and he'll be just as good a golfer as he's always been.
"And, if anything, it'll make him a better person than he already is, which is hard because he is already a great guy."
