We also already knew that Jason Quigley will meet Shane Mosley Jr in a middleweight bout, and today it was announced that we’ll also see Ronny Rios take on Oscar Negrete in a junior featherweight fight, plus returns for Bektemir Melikuziev and Azat Hovhannisyan, among others. Rios (32-3, 16 KO) has gotten himself back in the race at 122 pounds, winning three straight including an upset over previously-unbeaten Diego De La Hoya in July 2019. He unsuccessfully challenged Rey Vargas for the WBC belt in 2017, and looked pretty lousy in a stoppage loss to the aforementioned Hovhannisyan in 2018, but has bounced back nicely. At 30, he’s right in what should be his prime.
