Tomorrow in Cordoba, ten-rounder way the hell up at welterweight. Idk what the motivations are here (money, I'd wager) but this seems like a...not very good idea. He was last in action in 2010, granted on a three-win streak, but against meager competition (not horrible, just...well short of world class) at domestic level buffering him from his last defeat, on a championship rounds cuts TKO, by Rocky Juárez in 2008. As it stands, the Hyena lays claim to a very rare distinction in addition to having been a WBO super featherweight champion - he fought three HOF level talents in their primes, on fairly even terms, and reached at least the opening bell of a twelfth round with all three of them (stopped by Acelino Freitas in the final minute; and dropping a SD to Joan Guzmán before he met Rocky). Of his four career defeats, three were elites and the outlier (an early fluke DQ against César Emilio "Pirucho" Dómine) was avenged, by KO. Why mess with a perfectly decent legacy? Adailton De Jesus Conçeiçâo is only a year Barrios' junior, and has been absent from the ring himself nearly as long - since 2013. Still, the Brazilian glass cannon is the sort of guy, with all due respect to him, that Barrios would have annihilated with ease in his prime. It would be a shame to see the proud Argentinian warrior humbled in defeat at the hands of so lowly a foe, just by way of being rustier & more shot.
