The UFC’s September return to São Paulo is starting to take shape.

The UFC Fight Night 137 card, which is expected to air Sept. 22 on Fox Sports 1, is looking to add an exciting welterweight scrap between Belal Muhammad and Elizeu Zaleski dos Santos, per a report from Brazilian outlet Ag Fight. 

FloCombat independently confirmed the bout with sources close to the situation. 

Fresh off a victory at UFC Utica last month, Muhammad looks to bump his winning streak to five when he takes on surging Brazilian. 

Muhammad has not lost since UFC 205 in November of 2016, defeating Tim Means, Chance Rencountre, Jordan Mein, and Randy Brown during his latest stretch. The Palestinian-American is regarded by many to be on the verge of cracking the top 15. Most likely, a win over Zaleski would do just that. 

The Brazilian fighter is riding an impressive streak of his own, winning five consecutive bouts since dropping his UFC debut to Nicholas Dalby in 2015.

Most recently, Zaleski competed back in May, knocking out Sean Strickland with a spinning wheel kick at UFC 224.

In his six UFC appearances, Zaleski has won three Fight of the Night performances. Now paired with Belal Muhammad, there’s a good chance he picks up his fourth in São Paulo once the contracts are signed and the bout is finalized.
