Canadians Gillian (The Savage) Roberson and Serhiy Sidey have been added to a May 3 UFC Fight Night card in Des Moines, Iowa.

Robertson, ranked 12th among UFC strawweight contenders, will face No. 9 Marina Rodriguez of Brazil while Sidey tackles American bantamweight Cameron (The Baby-Faced Killer) Smotherman.

The main event at Wells Fargo Arena pits American Cory (Sandman) Sandhagen, ranked fourth among bantamweight contenders, against No. 5 Deiveson Figueiredo of Brazil, a former flyweight champion now campaigning at 135 pounds.

Robertson (15-8-0) won all three of her fights in 2024, defeating Brazilians Polyana Viana and Luana Pinheiro and American Michelle (The Karate Hottie) Waterson-Gomez.

The 29-year-old Robertson, who dropped to strawweight from flyweight (125 pounds) in early 2023, improved to 4-1-0 at 115 pounds. She is 12-6-0 in her UFC career.

Robertson was seven when her family left Niagara Falls, Ont., for Florida so her mother could take a nursing job. Robertson is now based out of Miami.

Rodriguez (17-5-2) has lost two straight and four of her last five. Before that she went 6-1-2 in the UFC.

Sidey (11-2-0) is 1-1-0 in the UFC after earning his contract in September 2023 with a KO win over American Ramon (The Savage) Taveras on "Dana White's Contender Series." Taveras won the rematch via split decision at UFC 297 in Toronto in January 2024.

The 28-year-old from Burlington, Ont., bounced back in November with a split-decision win over American Garrett Armfield.

Smotherman (12-4-0) won his UFC debut via decision over England's Jake (White Kong) Hadley in October.
