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
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
Emmett, Green has dropped back-to-back contests to Rustam
Khabilov and Michel
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.
