John Daly is in Florida to play in the PGA Tour’s Valspar Championship, and on Tuesday night Daly revealed that he knows exactly when he’ll undergo what is meant to be a random drug test. In a profane rant on SiriusXM PGA Tour Radio, Daly called out the commissioner of the PGA Tour and challenged the Tour to revise its drug testing policy, saying that all of the golfers know ahead of time when they’ll be subjected to a drug test.

“The problem is, and I’m actually defending all the golfers in this golf tournament. I’m so sick and tired of it being ‘random.’ It’s not ‘random.’ And [PGA Tour chief of operations] Andy Pazder, if you’re listening to the show, you and [commissioner] Tim Finchem get off your [expletive] and get it right. I’m tired of it because it has to be random. This is [expletive]. And I’m sorry, fine me, I don’t care what you do. Fine me, but do it randomly. I know when I’m getting drug tested. That’s sad. They all know when we’re getting drug tested. And for you dopers and all that [expletive] on the PGA Tour, you know you’re getting drug tested, you got it made!”
