UFC rankings updated after UFC 181: Johny Hendricks still better than Rory MacDonald

The official Ultimate Fighting Championship (UFC) rankings have been updated following UFC 181, which went down this past weekend (Sat., Dec. 6, 2014) in Las Vegas, Nevada.

Get full results here.

Anthony Pettis was successful in his first-ever lightweight title defense, as he choked out Gilbert Melendez in the second round of their co-main event championship fight (full highlights). As a result, "El Nino" dropped down a spot to No. 2, making way for Khabib Nurmagomedov to solidify himself as the next contender at No. 1.

Bring it!

In the welterweight division, Johny Hendricks coughed up his title to Robbie Lawler after five rounds of action (video), who now sits atop the 170-pound mountain while "Bigg Rigg" sits close behind at No. 1.

Elsewhere, the pound-for-pound rankings had plenty of movement including, you guessed it, Ronda Rousey and Anderson Silva exchanging spots for the third straight time.
