That didn't take long.
Just a couple of days removed from his first-round submission win over James Porter on Sept. 28, 2013, at NAFC: "Battle in the Ballroom" in Milwaukee, Wisconsin, Sergio Pettis will join older brother Anthony in the rank-and-file of Ultimate Fighting Championship (UFC).
The 20-year-old flyweight is expected to make his debut at UFC 167: "St. Pierre vs. Hendricks" -- as a bantamweight -- on Nov. 16 at MGM Grand Garden Arena in Las Vegas, Nevada, against Birmingham's Vaughan Lee, according to a report from Combate.
Pettis (9-0) has three wins as an undefeated amateur in addition to his perfect professional mixed martial arts (MMA) record, recently appearing for Ed Soares under the Resurrection Fighting Alliance (RFA) banner earlier this year in "Brew City."
Little fish, meet big pond.
Lee (13-9) is just 2-3 since making his promotion debut in November of 2011. The well-traveled Brit is coming off a second-round submission loss (armbar) to Raphael Assuncao as part of the UFC on FUEL TV 10 event earlier this year in Brazil.
Now he's got the chance to play spoiler.
"The Phenom," at one point, was waiting for his 21st birthday to qualify for The Ultimate Fighter (TUF), the combat sports reality show on FOX Sports 1 that can be a fast-track to bigger and better opportunities inside the Octagon, even without the "six-figure contract."
Not that it matters.
If he's anything like his older brother and reigning UFC Lightweight Champion "Showtime" Pettis, who also trains under famed MMA coach Duke Roufus, he's likely to end up with one anyway.
