Aamir Khan said he is yet to undergo four weeks of drug tests at his training camp to fight Kel Brook.
Welterweight rivals recently put pen to paper to confirm their bitter grudge match, scheduled for February 19, in Manchester.
And Khan, who is currently training in Colorado, revealed that the contract includes drug testing — often done at random — but hasn’t started the process yet.
He told IFL TV: “I sent a message to my wife the other day – I copied my lawyer into it too – saying, ‘Can you please push anyone, Skye or Boxer, Mr Shalom, Ben Shalom, saying that the test needs to be done’.
“I mean, I’m sitting here, there’s no testing happening, why? I’m waiting for the test. I’m the one who had to move it.
“I said, ‘Look, why weren’t the tests done? It’s a little weird.
“Testing is usually done when I work with WADA, or USADA in general, it’s done like straight.
“At a press conference they could have come. But for some reason, I’ve been in the camp for four weeks and no tests have been done, which I find quite strange.”

Sporting lawyer Geoff Cunningham insisted the trial for the fight is contracted, which is less than two months away.
Khan said: “Geoff Cunningham told me, look it’s there.
“But I’m not tested yet and it’s like my fifth week of training. And I’m like, ‘What’s going on?’
“We want to test, I want to test because it gives me the piece of mind knowing that it’s a fair fight.”
The 35-year-old pair have spent their entire careers tying each other up, and despite near-misses, a deal has never been finalized.

This means their rivalry continues to build and will now climax when the first bell rings next month.
But despite all the hostility over the years, Khan insisted that the feud and final fight were not personal and would not let emotions hinder his performance.
He added: “It’s business, nothing personal with Kel.
“When you let things get to you personally, you lose that game plan and go out there with a lot of hate and you want to hurt that person.
“I never want to make that mistake, I just want to go out there and smart box and do what I do best.”
