UFC fighter rankings: New welterweight champion Robbie Lawler enters P4P list

The biggest news from UFC 181 (aside from the CM Punk signing) was the shocking reality that Robbie Lawler will enter 2015 as the undisputed welterweight champion. Lawler wasn't even a welterweight from 2005-2012, and has been an absolute force since his UFC return in 2013. The rankings panel has placed Lawler 11th in the pound-for-pound rankings, right above Johny Hendricks, who loses his belt and drops to 12th on the list.

There weren't too many other changes directly from Saturday's show despite several ranked fighters being featured on the PPV. You can view the full rankings here. Fraser Coffeen is the sole Bloody Elbow representative on this week's panel.

Pound-For-Pound: Changes aplenty here. Ronda Rousey comes in at #7, which puts Anderson Silva down to 8th. Robbie Lawler's inclusion in the P4P list at #11 results in T.J.Dillashaw (#9) and Renan Barao (#10) to each climb one spot. Johny Hendricks falls the furthest from 9th to 12th, Vitor Belfort dips to 15th from 13th, and Dominick Cruz is knocked down from 12th to 13th.

Flyweight: John Lineker switches spots with Ali Bagautinov (again), as Lineker takes 6th. The same applies to Zach Makovsky and Tim Elliott, with the latter dropping to 10th.

Women's Bantamweight: Raquel Pennington's dramatic win puts her up a notch to 12th, while Germaine de Randamie falls to 13th. Holly Holm, who hasn't even fought yet in the UFC, goes up a spot to 14th while Leslie Smith rounds out the top 15.

Bantamweight: Takeya Mizugaki edges ahead of Eddie Wineland for 6th. Alex Caceres grabs 12th position over Erik Perez.

Featherweight: Charles Oliveira goes down a notch to 14th while Max Holloway ascends to 13th. Oliveira fights Jeremy Stephens (#10) this Friday.

Lightweight: Gilbert Melendez's loss to Anthony Pettis drops him to 2nd, while Khabib Nurmagomedov takes the #1 contender spot. Josh Thomson's tie with Edson Barboza for 6th was broken, as Thomson drops to 7th.

Welterweight: Johny Hendricks, championship belt now gone, is ranked #1 ahead of Rory MacDonald, who is likely Robbie Lawler's next opponent.

Middleweight: Thales Leites moves up to 11th ahead of 12th ranked Costas Philippou.
