Former two division world champion Timothy Bradley is backing Jermell Charlo to come away with a knockout victory on Saturday night, when he faces Brian Castano in a high stakes fight for the junior middleweight division.

Charlo and Castano will battle in San Antonio for the WBC, WBO, WBA, IBF world titles at 154-pounds.

Bradley has picked up on several flaws in Castano's style - and he believes Charlo will expose them.

"I think this fight is going to be very explosive. Charlo is a guy that can fight off his back foot, but also likes to attack. I think Charlo can mix things up, he works his combinations very well -- to the head and to the body. He's a very strong, very disciplined fighter," Bradley tells ESPN.

"Castano exposes himself too much for my liking. Being aggressive in the ring is great, but doing it at the right time, that's another thing. Castano tends to launch forward to attack and he makes the same mistake that a lot of other fighters make when launching forward -- he doesn't have a really good sense of range and where he needs to be at times. So at times he will launch forward and get exposed and get open for an uppercut. Charlo has a really good uppercut, and also a right hand. When Castano falls short with his offense he can run into a right hand -- and we know that Charlo's right hand is deadly."

Bradley is expecting Charlo not only to get the stoppage - but he expects him to close the show in explosive fashion.

"I think Charlo wins this fight in emphatic fashion and I think it is going to be a KO. Charlo wins in eight or nine rounds -- he's going to catch Castano with something nasty, either an uppercut or a straight right hand," Bradley said.
