UFC officials announced the new bout on Friday.
Makdessi (11-2) is fresh off of a victory over Daron Cruickshank at UFC 158, which followed up a win over Sam Stout at UFC 154. Those back-to-back victories ended a two-fight skid that had Makdessi’s UFC tenure teetering on the brink.
Makdessi is currently 4-2 in the Octagon, but UFC 162 will mark only the second time that he has fought for the UFC outside of his home country of Canada.
Barboza (11-1) had his spotless career smudged by Jamie Varner at 146 last year, but quickly bounced back with a first-round stoppage of Lucas Martins at UFC on FX 7 in Brazil in January.
