Instead, "Horror" has agreed to replace the injured Gunnar Nelson against Mike Pyle at UFC 160 next month, the UFC announced Tuesday.
Pyle (24-8-1) has won his last three fights in a row in rather impressive fashion, as he finished every fight in the first round. He most recently defeated James Head via first-round TKO in December.
UFC 160, headlined by Cain Velasquez vs. Antonio Silva 2 for the UFC heavyweight title, takes place May 25 at the MGM Grand Garden Arena in Las Vegas.
Update: Nelson's father and manager, Haraldur Nelson, told MMAFighting.com that Nelson injured his knee.
