According to MMAJunkie:

A bout between Anthony Johnson (7-2 MMA, 4-2 UFC) and fellow welterweight Yoshiyuki Yoshida (11-3 MMA, 2-1 UFC) will take place in October at UFC 104.

A source close to the negotiations today told MMAjunkie.com (www.mmajunkie.com) verbal agreements are in place and bout agreements are in the process of being finalized.

UFC 104, which features a main event between UFC light heavyweight champion Lyoto Machida and challenger Mauricio "Shogun" Rua, takes place Oct. 24 at the Staples Center in Los Angeles and airs on pay-per-view.

Now that should be a tough test for both men...very interesting match up if you ask me!

[Note by Kelvin Hunt, 07/14/09 4:31 PM EDT ]It is.  Also, I wonder what this means since Johnson was brought up on charges last week.  Zuffa must think he'll be in the clear in that regard?  Also, the rumored fight card for UFC 104 is as follows:

• Shogun Rua vs. Lyoto Machida
• Ryan Bader vs. Eric Schafer
• Kyle Kingsberry vs. Razak Al-Hassan
• Pat Berry vs. Antoni Hardonk

According to the new UFC Japan website, Yushin Okami vs. Chael Sonnen has now been added to the UFC 104 card.
