The UFC signed 20-year-old Sergio Pettis to its ranks after amassing a flawless 9-0 MMA record. He was the youngest fighter on the current UFC roster when he took on Vaughn Lee at UFC 167, and he was also among the youngest to have ever competed in the promotion.
We at MMA Insight have compiled a list of six of the youngest fighters to have ever fought for the UFC, and Pettis will be in a group of other stellar MMA stars.
1. Dan Lauzon
The younger brother of UFC lightweight Joe Lauzon, Dan Lauzon made his UFC debut as an 18-year-old against Spencer Fisher at UFC 164. It may have been a fight he lost, but Lauzon has gone on to have a fairly solid MMA career in the seven years since then.
He won eight straight MMA fights between 2007 and 2009, which resulted in a second shot at the UFC. That did not go so well for the younger Lauzon, having lost back to back fights to Cole Miller and Efrain Escudero.
However, he has not lost a fight since then, racking up five wins in a row and has now found a home at the World Series of Fighting (WSOF).
