Golf's world number three Justin Thomas revealed on Wednesday he had written to all his sponsors after issuing a public apology over an anti-gay slur that was caught on television microphones. Thomas is also planning to undergo a training program to ensure "he becomes a better person" after his comments at the US PGA Tour's Tournament of Champions in Hawaii this month. Obviously, I was upset. But at the end of the day, they have that right. They are a huge, huge global brand, and I have to respect their decision. It was obviously not calls or e-mails I was planning to make, but I needed to because I have some great long-lasting partnerships with all my sponsors.
