UFC 133 has come and gone, and the rankings have been adjusted as such.
We saw Rashad Evans maintain his No. 1 contender spot in the light heavyweight division, with a TKO victory over Tito Ortiz.
We also saw top featherweight prospect Chad Mendes earn a win over the Jiu-Jitsu specialist, Rani Yahya, in a fight that had real title implications.
So, who moved up, or even down in the pound-for-pound rankings in the aftermath of UFC 133?
In these rankings, fighters have been penalized and moved down for inactivity and significant periods of time for which they have not been actively competing. Fighters who have not been competing against "top level" talent have also been penalized.
This has been done because it is not fair for other fighters for another fighter to retain their position if they have not been actively competing.
By penalizing fighters for inactivity or for competing against a lack of "top-level" talent, it gives other fighters a chance to move up and stake their claim in the rankings.
So, without further ado, here are the top 25 pound-for-pound fighters in MMA right now.
