Two-time Olympian Daniel Cormier will make his mixed martial arts debut Sept. 25 at the third installment of Strikeforce: Challenger Series in Tulsa, Okla.

Cormier announced the news Monday via his official Twitter account. His opponent is TBA.

An aggressive freestyle wrestler, Cormier placed fourth in the 2004 Olympics and earned a record of 117-10 in collegiate competition for Oklahoma State University.

The Sept. 25 event is hosted by the SpiritBank Event Center and is headlined by a middleweight match-up between Tim Kennedy and Zak Cummings.
