Martin Day will replace Julio Arce and square off against Timur Valiev at UFC Fight Night 184 on Feb. 6.
The matchup was first reported by Rob Demello. UFC Fight Night 184 takes place at the UFC Apex in Las Vegas on Feb. 6 and is headlined by a heavyweight tilt between Alistair Overeem and Alexander Volkov.
Day is looking for his first promotional triumph after falling to Pingyuan Liu, Davey Grant and Anderson dos Santos in his first three appearances. The 32-year-old Hawaiian owns an 8-5 professional mark overall.
Valiev suffered a second-round KO loss to Trevin Jones in his Octagon debut at UFC on ESPN 15, but the result was overturned to a no contest after Jones tested positive for marijuana. The Dagestani had been victorious in his previous six pro outings, including wins in Professional Fighters League and World Series of Fighting.
