Former U.S. Open champ makes outrageous cheating claim about PGA Tour players: "No, it's true!"

Former U.S. Open champion Lucas Glover has claimed multiple PGA Tour members routinely cheat driver testing protocols. 

Aside from the brilliance of World No.1 Scottie Scheffler, the biggest talking point in recent weeks has been driver testing. 

Recently crowned Masters champion Rory McIlroy hit the headlines before the PGA Championship when it was revealed his TaylorMade Qi10 was deemed non-conforming by the United States Golf Association. 

McIlroy was forced to switch to a backup driver two days before the second men's major of the year began at Quail Hollow after his gamer failed a CT test. 

CT tests are used to measure how springy or flexible the face of the driver is when it strikes a golf ball. 

Because of the wear and tear and an increasingly thinning face, McIlroy's driver failed its test of legality. 

Three-time major champ Scheffler, 28, later revealed he his driver failed on the eve of the major but he was prepared for the scenario given he had been using it for more than a year. 

Former U.S. Open champion Glover, though, has accused several PGA Tour stars of being up to no good when he spoke about the topic on his Sirius XM radio show. 

"I've been trying to think all morning and all day how to say this without sounding like it's going to sound," he said. 

"But most guys don't give them their real driver anyway.

"They give them their backup just in case. No, it’s true. And the testing is the way it is, why, and again, I know a lot of guys, they keep two drivers in their bag just in case.

"Hey, oh, yeah – it's this one. It's this one right here. Yeah, do this, test this one.'"

In the immediate aftermath of his dominant PGA Championship victory, Scheffler argued there is no reason why every player shouldn't have their driver test every single week. 

"It's a newer rule that we haven't quite gotten right yet," he said. 

"I think we have some stuff to figure out, get more robust and get even more strict.

"You can test guys every week if you want. I mean, there's no reason why we shouldn't."

Glover agrees.

He said: "Why doesn't everybody get tested at every major? And why don't we somehow try to make sure it's the driver being used?"

"If we're going be on an equal playing field, and the four biggest events are going to bring all these people and all these tours together," Glover said, 

"Let's make sure we're playing under the same rules."

McIlroy has still not spoken about what transpired at Quail Hollow. 

Driver testing results are supposed to be kept confidential but someone leaked his to an American radio station. 

McIlroy made the cut on the number in Charlotte but failed to mount a challenge for the Wanamaker Trophy.

He did not speak to the media at all after each round.
