Easily handles opponent change

Dvorak defeated Juancamilo Ronderos via submission (rear-naked choke) at 2:18 of Round 1 at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Dvorak cruised to victory despite the fact his originally scheduled opponent, Raulian Paiva, was forced to withdraw following weight cutting issues on Friday morning. One of the more underrated fighters in the division, Dvorak easy took Ronderos' back following an exchange along the fence and quickly clamped on the rear-naked choke that ended the fight. The Brazilian fought it hard, but he never had a chance. The Czech Republic isn't a hotbed for mixed martial arts, but the soon-to-be 29-year-old Dvorak looks like the real deal.

Gets replacement for Saturday
FlyweightUFC
May 21, 2021
Dvorak will no longer be fighting Raulian Paiva at UFC Vegas 27 after Paiva was hospitalized Thursday following a brutal weight cut in preparation for the fight. Dvorak will now be fighting Juancamilo Randeros instead, Damon Martin of MMAFighting.com reports.
ANALYSIS
Dvorak's fight was expected to be removed from Saturday's card with the event set to get underway in a little over 24 hours but the UFC somehow got Ronderos to step in on extremely short notice. Ronderos owns a 13-fight win streak dating back to his amateur fighting days but Dvorak possesses an impressive streak of his own, as he's won 16 straight including his first two bouts as a member of the UFC.
Fighting in May

Dvorak will take on Raulian Paiva (knee) in a flyweight matchup at a UFC event scheduled for May 22, Marcel Dorff of MMADNA reports.
ANALYSIS
Dvorak will look to extend his winning streak after defeating Jordan Espinosa via unanimous decision in September. He's now won each of his last 16 fights and will take on Paiva in May. Paiva most recently defeated Zhalgas Zhumagulov via unanimous decision at UFC 251 in July but has been sidelined since then after undergoing knee surgery. The two fighters are even in height, but Paiva has a slight edge in reach.
Winning streak at 16

September 19, 2020
Dvorak defeated Jordan Espinosa via unanimous decision (30-27, 30-27, 30-27) at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
It's Dvorak's second straight win to begin his UFC run and his 16th straight overall. Knowing full well he was going up against an opponent who couldn't match him on the feet, Dvorak kept firing off combinations, including 37 leg strikes. The end result was a 69-50 edge in total strikes landed and a clear cut unanimous decision victory. Dvorak is just 28 years of age, but he deserves a step up in competition his next time out. He is going to continue to roll over these fringe-roster fighters for as long as the UFC puts them in front of him.
Set for Sept. 19 bout

Dvorak will square off against Jordan Espinosa in a flyweight matchup at UFC 253 on Sept. 19, Mike Heck of MMAFighting.com reports.
ANALYSIS
Dvorak is riding a 15-match winning streak and posted a win in his UFC debut versus Bruno Silva back in March, which came on short notice. Given that Espinosa has struggled on the mat at the UFC level and owns a one-inch height and reach advantage, it's possible Dvorak will make a few takedown attempts in this one after collecting none in his debut. An impressive win this time around would begin to boost him up the flyweight division rankings.

Dvorak defeated Bruno Silva via unanimous decision (29-28, 29-28, 29-28) at UFC Fight Night on Saturday in Brasilia, Brazil.
ANALYSIS
It was a solid, competent performance from Dvorak in his late-notice UFC debut. Knowing full well that Silva does his best work on the mat, Dvorak made a concerted effort to remain on the feet. For the most part, it worked. He did allow two takedowns but he quickly recovered to ensure Silva couldn't generate sustained momentum. Dvorak's gas tank look strong and he finished with a 50-33 edge in total strikes landed. He has now won his last 15 fights, with his last loss coming way back in May 2012.
