## Background and main event build-up
The original headliner matched Tybura, then ranked No. 8 among UFC heavyweights, with the Sydney-based fan favorite [Mark Hunt](https://www.edgepedia.org/mark-hunt). When Hunt was removed from the bout, Werdum, ranked No. 2 in the division, agreed to face Tybura on short notice.[3](https://www.ufc.com/news/werdum-flawless-unanimous-win-over-tybura) • [4](https://www.sherdog.com/news/articles/1/Preview-UFC-Fight-Night-121-Werdum-vs-Tybura-129211)
Werdum entered the bout in strong form. Five weeks earlier, at [UFC 216](https://www.edgepedia.org/ufc-216) in Las Vegas, he had submitted Walt Harris by armbar just 65 seconds into the first round, after [Derrick Lewis](https://www.edgepedia.org/derrick-lewis) withdrew from their scheduled fight on the day of that card.[3](https://www.ufc.com/news/werdum-flawless-unanimous-win-over-tybura) • [2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura) Tybura came in on a three-fight winning streak with only one UFC loss, having beaten former champion [Andrei Arlovski](https://www.edgepedia.org/andrei-arlovski) by unanimous decision at UFC Singapore in June 2017.[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura)
Fight week was also marked by an incident outside the fighter hotel in which Werdum threw a boomerang at fellow fighter [Colby Covington](https://www.edgepedia.org/colby-covington); the [New South Wales Police Force](https://www.edgepedia.org/new-south-wales-police-force) charged Werdum with common assault, and he was later fined $600 for the offense.[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura) • [1](https://www.sherdog.com/events/UFC-Fight-Night-121-Werdum-vs-Tybura-61985)
## The main event
Werdum controlled the fight largely on the feet, outlanding Tybura in nearly every round and barely needing his celebrated [Brazilian jiu-jitsu](https://www.edgepedia.org/brazilian-jiu-jitsu). He rocked Tybura several times, including in the fifth and final round, and his [Muay Thai](https://www.edgepedia.org/muay-thai) striking, particularly his knees, was described as the difference in the bout. Tybura landed multiple solid head kicks but could not follow up on them; the only round in which Werdum held a dominant ground position was the fourth, and Tybura worked his way back to his feet.[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura)
The judges scored the 25-minute fight 50-45 twice and 49-46 for Werdum. Afterward, Werdum, who had lost the heavyweight title to [Stipe Miocic](https://www.edgepedia.org/stipe-miocic) at [UFC 198](https://www.edgepedia.org/ufc-198) in May 2016, said he was seeking a title shot.[3](https://www.ufc.com/news/werdum-flawless-unanimous-win-over-tybura) • [2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura)
## Rest of the card
**Co-main event.** Jessica-Rose Clark, a bantamweight moving down to flyweight, won her UFC debut on 11 days notice, beating Australian countrywoman [Bec Rawlings](https://www.edgepedia.org/bec-rawlings) by split decision (29-28, 28-29, 29-28). A knee to the body in the second round turned the fight in Clark's favor. Rawlings had originally been scheduled against Joanne Calderwood, who withdrew about two weeks before the event.[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura)

Jake Matthews beat Bojan Velickovic by split decision, Alexander Volkanovski defeated Shane Young by unanimous decision (30-27, 30-26, 30-26), and Elias Theodorou beat Daniel Kelly by unanimous decision (30-28, 30-27, 30-26).[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura) • [1](https://www.sherdog.com/events/UFC-Fight-Night-121-Werdum-vs-Tybura-61985)
**Preliminary highlights.** Tai Tuivasa announced his UFC arrival by knocking out Rashad Coulter with a flying knee at 4:35 of the first round, keeping his record unblemished at 8-0 with every career win by some form of knockout. Nik Lentz submitted former Bellator champion Will Brooks with a guillotine choke at 2:05 of round two, and Ryan Benoit knocked out Ashkan Mokhtarian with a head kick at 2:38 of the third. Frank Camacho took a split decision over Damien Brown in a bloody, back-and-forth fight despite missing weight by four pounds.[2](https://www.mmafighting.com/2017/11/19/16675320/ufc-sydney-results-fabricio-werdum-wins-dominant-decision-over-marcin-tybura) • [1](https://www.sherdog.com/events/UFC-Fight-Night-121-Werdum-vs-Tybura-61985)
## Aftermath
