The former champion has won four of his last five fights and has been in the top 10 rankings on a consistent basis.
The win over "Big Nog" came after a flurry by the former PRIDE veteran that appeared to put Mir on his heels and came close to finishes in the first few minutes.
Mir battled and did what he usually does by locking his opponent in a submission after being dominated and getting the win. He did it to Tim Sylvia, he did it to Brock Lesnar and he just did it to Nogueira.
A dominant victory over a legend like Nogueira makes Mir the first person to ever make him tap and knock him out, a feat that screams future Hall of Fame status.
What is next for Mir? Here are a few fights that would make sense for him.
Reports coming out of the UFC 140 post-fight press conference suggested Alistair Overeem was pulling out of his UFC 141 fight with Brock Lesnar due to personal reasons.
"If the rumors that you're hearing are true, I wouldn't mind having to step in for Overeem and taking on Brock," said Mir. "I'm pretty healthy and three weeks isn't a bad turnaround."
That rumour was shot down, as reported in an article by MMAMania, that Overeem plans on "sending (Lesnar) back to the WWE" in his next bout.
No matter what happens in this fight, there is no question that Mir has entered talks of replacing the winner of this fight to go up against the new heavyweight champion Junior Dos Santos.
A Lesnar loss to Overeem could set up a trilogy bout between Lesnar and Mir. They both own victories over each other and a rubber match would be popular.
"I don't know how many heavyweights have three wins in a row against notable opponents with big names," said Mir at the UFC 140 post-fight press conference.
He is most definitely right on that one as his last three wins have been against Mirko Cro Cop, Roy Nelson and Nogueira, three guys who have been in title talks recently.
Mir also stated that his win should earn him a title shot if the Lesnar-Overeem doesn't meet expectations.
"If Lesnar lays on Overeem for three rounds, maybe I get the title shot and he doesn't," said Mir.
This fight would be a great No. 1 contender fight to meet the winner of Junior Dos Santos and Brock Lesnar/Alistair Overeem.
Velasquez is coming off the first loss of his MMA career and is looking to rebound against a perennial title contender.
A fight against Mir would be good for both men, as it will allow Mir to climb up in the rankings and for Velasquez it can show that he can come back from the lowest point of his career. It would also make the statement that he can't be rid of as easily as he was at the UFC on FOX event.
This fight would make the most sense for Mir.
