For their efforts, Stephens and Choi go home with an extra $50,000 and Fight of the Night.
Elsewhere on last night's bill - which drew an attendance of 10,052 to the Scottrade Center in St Louis - there were significant main-card victories for Jessica-Rose Clark, Kamaru Usman and in-form veteran Darren Elkins, who took his win streak to six.
After two long weeks, it finally arrived-the first UFC fight card of 2018.
Choi bloodied the nose of the ninth ranked UFC featherweight in the first round, but Stephens' toughness once again proved to be one of his most valuable assets as rallied to secure his second straight win. The duo trading some more shots before Stephens caught his opponent with a big hook that dropped Choi right to the canvas.
Stephens (27-14) delivered a jaw-dropping knockout against Doo Ho Choi on Sunday, finishing the Korean prospect with a pair of monstrous right hands in the second round.
It was another violent finish for a fighter who has made such things his hallmark. Although "The Korean Superboy" lost a unanimous decision, he picked up a lot of fans from around the world.
With this second-round TKO victory, Stephens builds on the momentum of a decision defeat of Gilbert Melendez.

Breaking and disrupting rhythm is difficult and unexpected, but Choi has a talent for it and does it often.
Doo Ho Choi made the walk to the "Superman" theme song, much to the delight of many on social media.
"I want a No. 1 contender, and I think that's realistic", Elkins said.
"Stuff doesn't matter", she wrote on social media in a post thanking the hundreds of users who helped spread the news. The 31-year-old American followed up with punches and elbows while in Choi's half-guard and the fight was swiftly stopped.
"I fought this fight, sitting at 30 percent", Usman revealed.
Choi (14-3), who's set for a lengthy lay-off as he prepares to complete his mandatory two-year military service in South Korea, has now suffered back-to-back losses. Choi is inching closer to Stephens, lands an uppercut and a strong leg kick. I have psychological advantages inside the Octagon as well, and that's something you can't take away. I just - I feel more like me. Right at that moment, Choi fired in his 17th and was rocked by a big right hand. It aired on FS1 following prelims on FS1 and UFC Fight Pass. Both guys come up firing.
