Justin Thomas and Jon Rahm are not keen to wear mics while they are playing professionally on the course.

The PGA Tour finally returns to action this week at the Charles Schwab Challenge. The New York Post reports that in the preamble, players are being asked if they would mind wearing a mic while playing to allow CBS TV some extra insight.

However, CBS has not been getting the answers they want.

"I would not wear a mic, no... that's not me," said Thomas.

"What I talk about with Jimmy [his caddie] and what I talk about with the guys in my group is none of anybody else's business, no offense.

"As close as those mics are on the tees and the greens, and as close as they get the boom mics during competition, I feel like I basically am mic'd up. I can't say some of the stuff I'd usually say. It's not that it's bad [but] if I want somebody to know what I've said, I'll say it in a press conference, I'll say it in an interview or put it out on social media."

Meanwhile, Rahm agreed with Thomas. The fiery Spaniard is known for his on-course expletives and was aghast to even be asked...

"You're asking me?" quipped the world No 2, Rahm.

"Selfishly, because who I am and because I know how I am on the golf course, I wouldn't support it, because there would need to be a 20- or 30- second delay. And I'm not the only one. A lot of people swear or cuss … I don't think it would be the best thing to do. I don't think there's any reason why we should be mic'd up from shot to shot.

"I see the point, but I think people expect us to talk about more interesting things than we really do. So I don't think it would be as entertaining as people think. It all depends. If somebody decides to do it and it really works out and it's fun, cool, go ahead.

"But I'm not speaking of many interesting things on the golf course."

Rahm and Thomas are part of the star-studded field - which includes world No 1 Rory McIlroy, Bryson DeChambeau and Jordan Spieth - who are set to tee-off at Colonial on Thursday.
