LAS VEGAS – UFC president Dana White said he continues to be impressed with the attitude and approach of the fighters at the Contender Series after the latest installment of the talent-finding series yielded four more signings. Antonio Arroyo , Ode Osbourne , Don’Tale Mayes and Brendan Allen all earned UFC deals after claiming impressive stoppage victories at the UFC Apex on Tuesday night, and White said he felt there could be little argument over the quartet he chose to sign. “If you look at the guys I took today… how do you not take these guys?” he asked reporters, including MMA Junkie, after the fights. “They all looked good.” The signings saw two complete newcomers – Osbourne and Allen – earn deals, while two fighters making return appearances at the Contender Series – Arroyo and Mayes – made the adjustments White was looking for to earn themselves contract offers. “What we’re looking for when guys come back is did you go back to the drawing board? Did you fix what was wrong?” he explained
