While Alistair Overeem failed an unexpected pre-fight drugs test at a recent UFC 146 press conference, his opponent and current heavyweight champion Junior Dos Santos had no such problems.

Now Dos Santos has given his initial reaction to the shock news regarding Overeem and has assured fans that they won’t be seeing any headlines of that nature regarding him in the future.

“I am professional and I’m champion without ever having used anything for better performance when you guys see me fighting that’s really me,” Dos Santos stated on Twitter.

With the fight now almost certain to be scrapped speculation is ramping up over who will come in to replace the Dutchman, but the Brazilian isn’t able to shed any new light on the situation.

“About what happened to Overeem, I don’t know anything more than you guys know and for me it’s between him and the Nevada Athletic Commission. I know a lot about me that’s it!”

What we do know is that Dos Santos will still defend his title at UFC 146 on May 26th as UFC president Dana White has confirmed that much.

The smart money would be on former champion Frank Mir getting the opportunity, though his originally intended co-main event opponent at the same show Cain Velasquez is also a possibility, while a pie-in-the-sky fan campaign to give Mark Hunt the fight has also kept the rumor-mill moving while we await an official announcement.
