Josh Taylor unified the 140 lbs belt, but he then decided to relinquished the WBC belt and now Prograis and Zepeda will have a chance to get this belt. Prograis lost to Taylor while Zepeda against Jose Ramirez, (and then Taylor beat Ramirez to get all the belts).
Prograis a huge favorite as per Stake @1.23, against Zepeda's odds @4.00
Zepeda is very durable as well so I expect this fight to be a war as this is for the belt. Although Prograis is also good, but it's going to be a close fight here.
Maybe the fight can go either direction in the judges scorecard, but I do agree, if someone who also look for a live underdog, it will be Zepeda in this fight.
