Strikeforce today unveiled heavyweight fighter Josh Barnett as their latest major signing.

The 32 year-old Barnett who holds a 26-5 record and is currently on a six fight winning streak significantly strengthens Strikeforce’s heavyweight roster and opens up a number of potential fights for the promotion, with Fedor Emelianenko, Alistair Overeem and Fabricio Werdum all likely match-ups for the former UFC and PRIDE veteran.

“Strikeforce is the home of the best heavyweight division in the world and I’m proud to be able to call it my home now,” Barnett stated in a press release to announce the signing.  “I’m looking forward to competing amongst the greatest fighters in the world and fighting my way to another world title.”

Of course Barnett does have a controversial past however, having tested positive for steroids numerous times during his career.  His last positive testing came prior to an eagerly awaited match-up with Fedor at an Affliction event last year.

Barnett has not fought in the US since and the subsequent canceling of that event brought an end to Affliction’s attempts to establish itself as an MMA promotion.  He has since fought both for DREAM and Impact FC overseas, picking up wins over Mighty Mo and Geronimo Dos Santos.

It seems that Strikeforce are willing to gamble on him though despite his prior troubles, and if he does steer clear of controversy then he certainly could be a valuable asset to them going forward.
