Strikeforce Heavyweight Champion Alistair Overeem has been released from his contract by the promotion, according to a report by Ron Kruck on Friday’s edition of “Inside MMA” on HDNet.

Strikeforce, according to the report, exercised its option to release its heavyweight champion with one fight still remaining on Overeem’s agreement.  The HDNet report also stated that Overeem, who withdrew from the Strikeforce Heavyweight Grand Prix Tournament due to a toe injury after he had defeated Fabricio Werdum via unanimous decision in a June 18 quarterfinal round tournament bout, has had additional health complications, including an injured rib and elbow.

Overeem has been unstoppable of late, winning the coveted annual K-1 World Grand Prix Final Tournament as well as the Dream championship.  He has not lost since being stopped by Sergei Kharitonov in 2007.

Earlier in the week, United Glory announced that Overeem would be competing in its next event in Moscow, Russia on an October date to be announced.
