The Las Vegas-based promotion announced the contests on Monday. UFC Fight Night 131 takes place on June 1 at Adirondack Bank Center in Utica, N.Y., and is headlined by a bantamweight tilt between Jimmie Rivera and Marlon Moraes. The card airs on Fox Sports 1 following early prelims on UFC Fight Pass.
Tibau is currently on a three-bout skid, including a 57-second knockout loss to Islam Makhachev in his most recent outing at UFC 220 on Jan. 20. After beginning his Octagon tenure with a split-decision win over Josh Emmett, Green has dropped back-to-back contests to Rustam Khabilov and Michel Prazeres.
Lentz last appeared at UFC Fight Night 121 this past November, where he submitted ex-Bellator champ Will Brooks with a rear-naked choke in the second round to give him three wins in his last four outings. Santos, meanwhile, is unbeaten in six UFC bouts – including a first-round stoppage of Kevin Lee – but hasn’t competed since October 2016.
