UFC lightweight Evan Dunham (18-7-1) took to his Instagram account to reveal that he plans to retire after his bout with Francisco Trinaldo (22-6-0) at Sao Paulo’s UFC Fight Night 137.

Dunham, 36 is winless in his last two fights (0-1-1), but has compiled an 11-7-1 record in the octagon against some of the best names in the division in just under 10 years of competition. He joined the UFC in February 2009, winning his first bout via TKO at UFC 95. He will likely be remembered for some memorable fights against Tyson Griffin, Donald Cerrone, and Edson Barboza.

Trinaldo, who hails from Curitiba, Brazil, likely has other ideas. The 39-year-old has lost two of his last three fights, including a decision to James Vick at UFC Fight Night 126 in February. He will have the hometown  advantage.

UFC Fight Night 137 is scheduled for Sept. 22 at the Ginasio do Ibirapuera in Sao Paulo, Brazil. Tentative bouts include:

Mark Godbeer (13-4-0) vs. Luis Henrique (10-4-0)

Glover Teixeira (27-7-0) vs. Jimi Manuwa (17-4-0)

Alex Chambers (11-1-0) vs. Livia Renata Souza (5-4-0)

Elizeu Zaleski dos Santos (19-5-0) vs. Belal Muhammad (14-2-0)

Sam Alvey (33-10-0) vs. Antonio Rogerio Nogueira (22-8-0)

Francisco Trinaldo (22-6-0) vs. Evan Dunham (18-7-1()

Thales Leites (27-9-0) vs. Hector Lombard (34-9-1, 2 NCs)

Neil Magny (21-6-0) vs. Alex Oliveira (18-5-1)
