UFC officials have signed Darrell Horcher to face Khabib Nurmagomedov at UFC on FOX 19 next Saturday night.

Nurmagomedov was slated to face Tony Ferguson in the main event, but a lung injury forced Ferguson out. After an initial report indicated Donald Cerrone would step in, officials elected to bring in Horcher instead.

Horcher (12-1) is on a five-fight win streak and is a former Bellator competitor. The 28-year-old will meet Nurmagomedov at 160 pounds.

Nurmagomedov (22-0) has been on the sidelines since a win last year over current UFC champion Rafael dos Anjos. He is a perfect 6-0 inside the Octagon.
