Tony Ferguson defeated Donald "Cowboy" Cerrone in their lightweight bout at Saturday night's UFC 238 in Chicago due to a doctor's stoppage in the second round.
The official result was ruled a technical knockout.
The fight was stopped because Cerrone couldn't open his right eye.
Cerrone blew his nose, and the eye subsequently swelled shut because of other facial injuries:
Brett OkamotoThis is tough. Tony looks angry. Fight is stopped because of Cowboy's eye. He blew it and it closed up on him. Tony looks disgusted. He landed that late blow after the second round.
