Vallejos’ rapid rise as an undefeated featherweight prospect with four straight UFC wins, including first-round finishes over Giga Chikadze and Josh Emmett, has opened multiple high-profile options in the 145-pound division. This keeps the market tightly bunched around Yair Rodriguez, Arnold Allen, and Youssef Zalal because each represents a distinct stylistic test and ranking boost that aligns with UFC matchmaking priorities for advancing the Argentine toward title contention. Recent form, reach and power advantages, plus scheduling flexibility for late 2026 bouts sustain the competitive dynamics, as any of these matchups could serve as a proving ground without rushing Vallejos prematurely. Lower-probability names like Aljamain Sterling and Steve Garcia remain viable but trail due to less direct stylistic or divisional fit.
