Officials announced the bouts earlier this week, but didn't clarify a specific placement on the fight card.
Barnatt (6-0), a first-round pick and eventual quarterfinalist on The Ultimate Fighter (TUF) 17, secured a UFC contract when he scored a unanimous decision victory over Collin Hart at the show's live finale last April. The English fighter also has four stoppages.
Craig (9-1), meanwhile, is a former Legacy FC champion who had a successful start to his UFC career. After wins over Kyle Noke and Rafael Natal in his first two Octagon appearances, he suffered a decision loss to Ronny Markes. However, in his most recent bout, he rebounded with a split-decision victory over Chris Leben at UFC 162.
Kuiper (12-2) opened his MMA career with an (11-0) record, which earned him a much-deserved UFC contract. In his debut, he suffered a decision loss to Natal before rebounding with a technical knockout victory over Jared Hamman. In his most recent bout, Tom Lawlor defeated him via submission at UFC on FUEL TV 9.
He looks to come back again when he meets Scott (8-2), who went 8-1 with eight stoppages before signing with the UFC, but hasn't fought since December.
UFC Fight Night 30 will be the second international event for the organization in the United Kingdom this year, featuring a plethora of other bouts at the moment that include Melvin Guillard vs. Ross Pearson and Ryan Jimmo vs. Jimi Manuwa, as well as the middleweight main event of the evening between Michael Bisping vs. Mark Munoz.
