Gunnar Nelson, who trains with Conor McGregor, will co-headline UFC Fight Night at The O2 in London on March 18.

The No. 9-ranked welterweight will face Alan Jouban as a joint-main event with Jimi Manuwa's light-heavyweight bout against Corey Anderson.

Nelson, who was born in Iceland but trains alongside McGregor in Ireland, goes into the contest on the back of a second-round submission win over Albert Tumenov last May, while Jouban, of the U.S., is aiming for his fourth win in a row.

British fighter Manuwa, meanwhile, returns to the Octagon against Anderson after a second-round stoppage over Ovince Saint Preux in his last outing, at UFC 204.
