MOSCOW – Undefeated up-and-comer Jordan Johnson could be gone from the UFC after a thrilling victory at UFC Fight Night 136.

Johnson (10-0 MMA, 4-0 UFC) finished his UFC contract Saturday when he defeated Adam Yandiev (9-1 MMA, 0-1 UFC) by second-round submission. The middleweight bout was part of the UFC Fight Pass-streamed card from Olympic Stadium in Moscow.

Although Johnson, 29, said he would prefer to stay in the UFC, he was not pleased with a previous extension offer from the organization. He hopes a dominant performance and finish will make a difference going forward, but he’s prepared to go elsewhere if not.

“This could be my last fight here,” Johnson told MMAjunkie post-fight. “I’d like just a little bit more money. I know in some of these interviews I’ve done, I’m an unfamiliar face, I seem a little grumpy, but I’m going to enjoy it.”

Johnson did not reveal the exact financial terms of the UFC’s offer, but he made it clear he knows what he wants. He believes his previous fights in the octagon may have led to a lesser offer, but he said the submission of Yandiev should serve as an eye-opener.

“I just know I’m worth a little bit more,” Johnson said. “I laid a nice bet on myself wanting to come out and show that I am a finisher against these guys in the UFC. I had a real dominant first performance, and then I didn’t perform the way I wanted to in my last two outings.”

The win over Yandiev marked Johnson’s successful middleweight debut. He started his career at heavyweight and has worked his way down to 185 pounds. He said another drop in weight class could be on the horizon but added that he would fight in any division so long as he gets real competition.

Johnson said he’s in no rush to get his new deal done, but assuming he stays with the UFC, he wants a step up in competition.

“Who do I want to fight at middleweight? There’s a lot of guys,” Johnson said. “I was heavyweight coming down. I don’t know what this win would do for me in the rankings. Slide me in. But first things: I could fight at light heavyweight, I could fight at heavyweight too. I’m still a little bit chubby, you might see me at welterweight. I’m going to figure it out. Wherever I’m at I want a nice, ranked opponent. Someone who is supposed to beat me, and I want to (expletive) him up.”
