Former UFC heavyweight fighter Mike Russow has signed a multi-fight deal the World Series Of Fighting promotion.

The 36 year-old had a four year stint in the UFC, going 4-2 during that time. His most memorable fight came in May of 2010 when he appeared to be getting soundly beaten by the at the time highly touted prospect Todd Duffee, before suddenly coming to life mid-way through the third round, flooring him with a single punch to claim one of the biggest come-from-behind victories in recent times.

After winning his first four fights in the UFC things started to go downhill rapidly for him however, dropping to a first round TKO loss to Fabricio Werdum last year and then a second round TKO stoppage against Shawn Jordan back in January.

Those back-to-back losses signaled an end to his time in the Octagon, but rather than hang up his gloves for good and concentrate on his day job as a Chicago police offer, Russow has opted to continue on in the sport with the WSOF promotion.

The World Series Of Fighting heavyweight roster could certainly use another familiar face to offer up new challenges for the likes of Andrei Arlovski and Anthony Johnson who’ve recently fought in the division along with the likes of Mike Kyle, Rolles Gracie, Dave Huckaba and Ray Sefo.

So far no opponent or date has been confirmed for Russow’s WSOF debut.
