The latest UFC rankings have been released, and Matt Brown has climbed one position at welterweight to No. 6. Brown, coming off a third round TKO over Erick Silva, leapfrogged Hector Lombard.

“The Immortal” has won seven straight fights, including six via finish. Silva slipped one position to 15th overall.

A host of other fighters moved up or down after the event, including Rustam Khabilov climbing three spots in the lightweight Top-15 despite not fighting. Nate Diaz and TJ Grant were both removed from the rankings due to inactivity recently.

Kyoji Horiguchi, who defeated Darrell Montague, moved into the flyweight rankings at No. 14, while Montague bowed out after his second consecutive loss. Johnny Eduardo, fresh off finishing then-No. 4 Eddie Wineland at UFC Fight Night 40, debuted at No. 12 this week.

At middleweight, Lyoto Machida and Vitor Belfort flipped second and third again. The two reversed their current stand two weeks ago when the rankings were updated. Costas Philippou climbed to 10th after defeating Lorenz Larkin.

In the featherweight division, Chan Sung Jung, Clay Guida and Dennis Bermudez all improved one spot, while Dustin Poirier, Dennis Siver and Jeremy Stephens dropped one position each.

The rankings are voted on by members of the MMA media and others, and each set of rankings can be viewed on the UFC’s site. While they serve a purpose for discussing possible future match ups and contenders, they are not a be-all, end-all deciding factor when it comes to pairings.

The next set of rankings will be updated after UFC 173 in two weeks.
