Stuns Tai Tuivasa at UFC 243
October 5, 2019
Spivac defeated Tai Tuivasa via submission (arm-triangle choke) at 3:14 of Round 2 at UFC 243 on Saturday in Melbourne, Australia.
Spivac lasted all of 50 seconds in a knockout loss to Walt Harris in his UFC debut in May, so it would have been an improvement if he lasted even a minute against Tuivasa. Instead, he exploited his opposition's weakness. Instead of standing and trading with the powerful Tuivasa, Spivac leaned on his wrestling. He scored on six-of-eight takedown attempts and exhausted the out-of-shape Tuivasa with his work on the mat. Even if this result was a bit of a fluke, it's going to earn Spivac a big fight his next time out. It was a stellar effort from a guy who entered as a +270 underdog.

Booked against Tuivasa for UFC 243
July 23, 2019
Spivac (9-1-0) will take on Tai Tuivasa (8-2-0) at UFC 243 in Melbourne on October 5, Nolan King of reports.
Spivac has fought just once in the UFC and is coming off a 60-day medical suspension. He struggled in his debut, as he did not last one minute against Walt Harris (13-7, 1 NC). However, he will face off against Tuivasa, who is struggling in his own right, coming off two consecutive losses. Tuivasa did come into the promotion with quite a bit of hype, so look for Spivac to enter as a betting underdog.
Handed 60-day suspension
May 7, 2019
Spivak (9-1-0) received a 60-day medical suspension after sustaining unspecified injuries Saturday in his TKO loss to Walt Harris at UFC Ottawa, Steven Marrocco of reports.
The medical suspension shouldn't have much bearing on Spivak's plans, as it's unlikely he would have re-entered the Octagon within the next two months even if he avoided injury and kept his undefeated record intact over the weekend. Spivak may look to find an easier opponent for his next bout after Harris beat him decisively in the 50-second fight.
No-shows UFC debut Saturday
May 4, 2019
Spivak lost to Walt Harris via TKO (punches) at 0:50 of Round 1 at UFC Fight Night on Saturday in Ottawa.
If any debuting fighter doesn't deserve a second chance with the company, it's Spivak. The big man literally did nothing for the 50 seconds the fight lasted. FightMetric credited Spivak with three strikes attempted, but you would be hard pressed to find them if you watched the replay. It's scary to think that Spivak entered Saturday's fight undefeated.
To face Walt Harris
April 9, 2019
Spivak will fight Walt Harris at UFC Ottawa on May 4, Alexander K. Lee of reports.
Spivak is a perfect 9-0 in his professional fighting career, winning every bout by either knockout or submission, per Lee. The Moldova native racked up most of those wins under the banner of World Warrios Fighting Champion. He'll have his hands full against Harris, who has fought in the UFC nine times since his 2014 debut. The results have largely been mixed, as Harris recently recorded a victory over UFC legend Andrei Arlovski, though it was later ruled a no-contest after a failed drug test (due to a contaminated supplement).
