UFC rankings updated after UFC Fight Night 63: Julianna Pena improves, but still not top 10

The official Ultimate Fighting Championship (UFC) rankings have been updated following the UFC Fight Night 63 event, which went down this past weekend (Sat., April 4, 2015) on FOX Sports 1 from inside the Patriot Center in Fairfax, Virginia.

For complete "Mendes vs. Lamas" results and play-by-play click here.

Not surprisingly, Chad Mendes held his spot atop the 145-pound leaderboard, thanks to a blistering first-round knockout that left Ricardo Lamas standing fast at No. 4 (video). "Money" is likely to get the winner of Jose Aldo vs. Conor McGregor, who compete at UFC 189 for "Junior's" belt.

That's not all.

Julianna Pena returned from her extended injury layoff to beat the brakes off bantamweight prospect Milana Dudieva (watch it). With her second-straight dominant performance, the "Venezuelan Vixen" takes hold of the No. 11 spot at 135 pounds.

A few more like that and it will be time to get "Rowdy."

Here's what the rest of the field looks like courtesy of UFC.com. Note: (+/- = movement in rankings, *NR = Not previously ranked).
