The UFC Fight Night 137 card has taken all kinds of hits in recent weeks, but the promotion is attempting to salvage the card with some late additions.

The organization has confirmed a lightweight booking between Charles Oliveira (23-8 MMA, 11-8 UFC) and Christos Giagos (15-6 MMA, 1-2 UFC). A heavyweight matchup, reported first by FloCombat.com and later confirmed by both fighters, between Chase Sherman (11-5 MMA, 2-4 UFC) and Augusto Sakai (11-1-1 MMA, 0-0 UFC) will also go down on next month’s card.

UFC Fight Night 137 takes place Sept. 22 from Ibirapuera Gymnasium in Sao Paulo, Brazil. The card airs on FS1 following early prelims expected on UFC Fight Pass.

Oliveira, 28, is tied with Royce Gracie for the most submission wins in UFC history (10). He finished Clay Guida in the first round of his most recent bout at UFC 225 and will try to take sole possession of the record in his upcoming matchup. He will have to get through Giagos, though. The 28-year-old will return to the UFC for the first time since June 2015 after going 4-2 outside the organization.

Sherman, 28, will attempt to buck a two-fight skid at UFC Fight Night 137. He hasn’t won since July 2017 but hopes to get back on track against the debuting Sakai, 27, who earned his UFC contract with a second-round TKO on Dana White’s Contender Series Brazil 1 this month.
