Anderson Silva Jumps the Gun ... No Decision Yet on Cormier's UFC 200 Opponent

Anderson Silva is boasting he's the one who was picked to replace Jon Jones in the UFC 200 fight against Daniel Cormier, but our UFC sources say no decision has been made.

We're told there are 3 contenders for the spot and Silva is indeed one of them. But UFC honchos are still meeting and they haven't picked anyone at the time of this post.

We're told there's a complication for Silva ... he just had gallbladder surgery and there are questions about his physical fight-worthiness for a match in just 48 hours.

BTW, further proof nothing is official, the picture Silva posted is just the UFC 200 meme generator .... which anyone can use.

Look who's also "in the running" ...

We'll let you know when the decision's really in ... stay tuned.
