UFC Fight Night: Smith vs. Rakić

UFC Fight Night: Smith vs. Rakić (also known as UFC Fight Night 175, UFC on ESPN+ 33 and UFC Vegas 8) was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on August 29, 2020, at the UFC Apex facility in Enterprise, Nevada, part of the Las Vegas Metropolitan Area, United States.

Promotion officials were originally targeting a featherweight bout between The Ultimate Fighter: Latin America featherweight winner Yair Rodríguez and Zabit Magomedsharipov to serve as the event headliner. However, Rodríguez pulled out of the bout on August 5 with an ankle injury and Magomedsharipov announced he would not fight at the event. The pairing was first scheduled to take place at UFC 228 in September 2018, but Rodríguez also pulled out of that event with an injury. The pairing was rescheduled for UFC 254.

On August 15, it was announced that a light heavyweight bout between former UFC Light Heavyweight Championship challenger Anthony Smith and Aleksandar Rakić would serve as a three-round main event.

Emily Whitmire was scheduled to face Polyana Viana in a women's strawweight bout at UFC 248 earlier this year. However, Whitmire weighed in at 117.5 pounds, one and a half pounds over the strawweight non-title fight limit. She was subsequently hospitalized the day of the event, thus cancelling the fight. The pairing was rescheduled for this event instead. It was reportedly rescheduled as a women's flyweight bout, but ultimately took place as a women's strawweight contest.

A featherweight bout between former UFC Featherweight Championship challenger Ricardo Lamas and The Ultimate Fighter: Team McGregor vs. Team Faber lightweight winner Ryan Hall was also scheduled to initially take place earlier this year at UFC Fight Night: Hermansson vs. Weidman, but the event was cancelled in mid-March due to the COVID-19 pandemic. The pairing was rescheduled for this event. In turn, Hall pulled out due to undisclosed reasons a week before the event. He was replaced by promotional newcomer Bill Algeo.

A welterweight bout between Neil Magny and Geoff Neal was scheduled to take place at this event. However, Neal withdrew from the event on August 9 due to a severe case of pneumonia that evolved to sepsis. He was replaced by former UFC Welterweight Champion Robbie Lawler. The original pairing is now expected to take place at UFC on ESPN: Rodriguez vs. Waterson

A light heavyweight rematch between Magomed Ankalaev and Ion Cuțelaba was expected to take place at this event. The pair first met at UFC Fight Night: Benavidez vs. Figueiredo, where Ankalaev won via controversial knockout. The bout was originally expected to take place at UFC 249, on its original April 18 date. However, Ankalaev was forced to pull out of the event due to travel restrictions related to the COVID-19 pandemic. They were later rebooked for UFC 252, but Cuțelaba then pulled out after he tested positive for COVID-19 and the bout was rescheduled for this event. Cuțelaba tested positive yet again on the day of the event, resulting in another cancellation of this fight.

A featherweight bout between Alex Caceres and Giga Chikadze was initially scheduled to take place three weeks earlier at UFC Fight Night: Lewis vs. Oleinik, but was pushed back to this event due to undisclosed reasons. In turn, Chikadze withdrew from the bout on August 26 after testing positive for COVID-19 and was briefly replaced by promotional newcomer Kevin Croom. Subsequently on the following day, Croom was removed and replaced by fellow newcomer Austin Springer.
