Alistair Overeem passed his drug test for Strikeforce “Heavy Artillery” just like he said he would.

Strikeforce heavyweight champion Alistair Overeem has tested negative for anabolic steroids and drugs of abuse based upon independent testing that was administered by the promotion, CEO Scott Coker told on Friday.

An independent on-site technician from a local laboratory conducted the urinalysis screening in the event’s host hotel following the official weigh-ins last Friday.

Results from the Missouri-administered test that Alistair may or may not have taken won’t be released to the public unless he tests positive, but that seems very unlikely given the results of the in-house drug test.

The rest of the main card fighters were also tested. Antonio Silva, Joey Villasenor, Ronaldo “Jacare” Souza, Rafael “Feijao” Cavalcante and Antwain Britt all tested clean, while the results for Brett Rogers, Andrei Arlovski, Roger Gracie, and Kevin Randleman are still pending.
