Weight Class: Welterweight In the co-main event of the evening, Icelandic jiu-jitsu specialist Gunnar Nelson (12-0-1), who trains with headliner Conor McGregor at SBG Ireland under John Kavanagh, takes on TUF 17 alum Zak Cummings (17-3). At first glance, this one looks like a bit of a gimme fight for Nelson, but Cummings, who wasn't exactly a standout during TUF 17, has won both his fights in the UFC to date. Cummings has also fought as high up as light heavyweight, so there's a bit of a size advantage, but his jiu-jitsu doesn't come close to the level of Nelson, a black belt who has won gold medals in jiu-jitsu at the Pan American Championship. Cummings has a brown belt of his own and several submission wins, but when this goes to the mat, Nelson will come out on top. Gunnar by submission, in the third.
