Junior dos Santos can still deliver fierce blows, and Tai Tuivasa learned that the hard way, as the former UFC heavyweight champion captured a second-round TKO victory in the main event of UFC Fight Night 142 in Adelaide, Australia, on Saturday night (Sunday in Australia).

Dos Santos improved to 20-5 lifetime with the defeat, and he secured his first win via knockout since he downed Mark Hunt in their clash at UFC 160 in May 2013.

"I have knockout power and I can knock anyone out!" dos Santos said, according to ESPN.com's Brett Okamoto.

The 34-year-old has now won two fights in a row and three of his last four overall dating back to April 2016. Tuivasa, meanwhile, suffered his first professional loss and dropped to 8-1 with the defeat.

Here's a look at the rest of the evening's results, including a spotlight on a couple of notable newcomers.

Jim Crute Enters Record Books with Late Stoppage

Jim Crute made his UFC debut on Saturday night, and he did so in style.

Already in possession of an 8-0 lifetime record, Crute nudged his way up to 9-0 as he defeated Paul Craig thanks to a third-round submission that was the fourth-latest in modern light heavyweight history, according to the UFC:

"I'm here to stay," Crute said after his maiden win with the promotion, via Sherdog. "The UFC is my home."

Now the owner of six stoppages (three via submission and three knockouts) in nine career fights, Crute has to be on the light heavyweight radar when the calendar flips over to 2019.

Yusuff Makes Power-Packed Statement

Speaking of debuts, Sodiq Yusuff announced his presence with authority as he laid into Suman Mokhtarian with a flurry of vicious punches and grabbed a swift first-round victory via TKO.

"Sooner or later it was going to get worse and worse," Yusuff said of the early stoppage, via MMA Fighting. "The referee has to look out for our safety."

The 25-year-old still has a ways to go if he wants to entrench himself as a contender in UFC's star-studded featherweight division. However, he certainly made all the right moves in Adelaide.

As a result, he should be poised to start his ascent behind explosive tactical skills that can strike fear into some of the class' more dynamic fighters.
