Chris HumphreyJun 6, 2018

With some of the old guard of the MMA world riding off into the sunset, the new guard is making a definite impact as they try to fill the shoes of the former champions and legends.

As the new fighters start to make waves in promotions across the world, they are quickly making a name for themselves within the MMA community—like Jon Jones, who will challenge Mauricio Rua for the Light Heavyweight Championships this Saturday at UFC 128.

Also after the absorption of the WEC into the UFC, popular newcomers Jose Aldo and Dominick Cruz will both enter the UFC as the first time champions of their respective weight classes as the promotion expands the current roster.

With that said, let's take a look at the aforementioned fighters along with the rest of the list of best young MMA fighters that are putting the respective divisions on notice.
