On Saturday, Caleb Plant and Jermall Charlo will look to avoid the pitfalls faced by Devin Haney and Ryan Garcia with the intent to make a big showdown later this year.

Jermall Charlo, who grew up in Alief, returned to boxing and stopped Thomas "Cornflake" LaManna, but his future bout with Caleb Plant was wrecked by an upset.

May has been a month of major upsets in boxing — and Armando Resendiz's shocking victory over Caleb Plant may be the biggest of them all.
