Finally, via USA TODAY:

Barely a week before it's scheduled to happen, Siala "Mighty Mo"
Siliga has agreed to face heavyweight Josh Barnett. 

Siliga has signed the contract for a fight with Barnett at Dream 13
on March 22 in Yokohama, Japan, manager Steve Rusich told MMA Weekly and MMAjunkie.com. SI.com's Josh Gross earlier this week posted news about a possible bout
between Siliga and Barnett. 

…

The 39-year-old Siliga (3-1) hasn't competed in MMA since New Year's
Eve 2008, when he was submitted by fellow K-1 kickboxer Semmy Schilt
with a triangle choke. Siliga has had his share of success in the
kickboxing world, including K-1 World Grand Prix tournament
championships in 2004 and 2007.

This is yet another less than stellar opponent for Barnett. He last
fought MMA in January of 2009 against Gilbert Yvel. Prior to that he
faced Pedro Rizzo, Jeff Monson and Hidehiko Yoshida. Barnett hasn't
faced a top ten opponent since losing to Rodrigo Antonio Nogueira on New
Year's Eve 2006. He hasn't beaten a top ten opponent since beating
Nogueira by split decision in September 2006.

Hopefully Barnett will straighten out his issues with the California
State Athletic Commission and be able to once again fight in the
States. 

Failing that, I would like to see him face more credible opposition
in Japan. It's too bad Tim Sylvia turned down a DREAM.13 fight with
Barnett. The winner of that fight would have definitely been back on
track.

There is also always the outside possibility that DREAM will put
together the money to book Fedor Emelianenko vs Josh Barnett sometime
this year or next as well.
