'Cowboy' Cerrone throws his hat in the ring to fight Nurmagomedov

The UFC has a volunteer to fill in for Tony Ferguson against Khabib Nurmagomedov on April 16, and he's a familiar face.

Donald "Cowboy" Cerrone offered up his services over Twitter on just 10 days notice and would be moving back to lightweight after a February win at welterweight over Alex Oliveira.

Cerrone has had five fights since January of 2015, going 4-1 over that time, dropping his only title shot against Raphael dos Anjos in December.

Nurmagomedov has been waiting to fight Ferguson since last year when he had to pull out of a Dec. 15 bout due to injury. It's now unlikely that fight will happen any time soon.
