Casey currently rides a six-fight undefeated streak, but that run is marred by two no-contests. The first, a UFC 175 bout against Bubba Bush, was originally ruled a knockout victory for Casey, but the result was overturned after the former The Ultimate Fighter competitor tested positive for the anabolic steroid drostanolone after the fight.
More recently, Casey competed at UFC Fight Night 80, getting just 11 seconds of cage time before an eye poke from his opponent, Antonio Carlos Junior, halted the fight.
Now, Casey turns his attention to Natal to rebound from this unfortunate finish in his last outing.
UFC on FOX 18 is headlined by a light heavyweight tilt between Anthony Johnson (20-5) and Ryan Bader (20-4). Heavyweights Ben Rothwell (35-9) and Josh Barnett (34-7) will clash in the night's co-main event.
