Francis Ngannou has taken over the No. 2 spot in ESPN's heavyweight rankings, thanks to the recent retirement of former UFC champion Daniel Cormier.

At light heavyweight, Dominick Reyes has grabbed the second spot after the August defeat of ex-Bellator champ Ryan Bader.

Those represent the highest level of flux in the rankings, but there's also a new entrant in the men's bantamweight top 10 whom you might have heard of: Frankie Edgar. The former UFC lightweight champ earned his spot in a new division with an Aug. 22 win over Pedro Munhoz, who drops one spot in the rankings.

In addition to Cormier, other fighters to fall out of the rankings include unbeaten strawweight Tatiana Suarez and Nina Ansaroff, neither of whom has competed since they met in June 2019.
