UFC 181 plays host to the lightweight title tilt between champion Anthony Pettis and No. 1-ranked contender Gilbert Melendez.
The two fighters are coming off coaching The Ultimate Fighter’s 20th season, and they got in each other’s face at the UFC 181 weigh-ins on Friday evening. The Vegas crowd was pro-Melendez at the weigh-ins, but it may be more even come fight day.
This will be Pettis‘ first defense of his crown since winning it last year against Benson Henderson.
Bleacher Report will have complete coverage of the co-main event when it gets underway Saturday night.
