Uzcategui is 28-2 with 23 KO’s. In the his first loss, Matt Korobov beat him well, suffering two knockdowns. Uzcategui was dominating the Dirrell fight, but hit Dirrell after the bell and disqualified. In the rematch with Dirrell, Uzcategui took care of business but surprisingly (to me) didn't stop Dirrell. He is a rugged hunter with a big right hand and rarely takes a step backwards. He has no foot or side to side movement but sports a good chin. He likes to play the bully in the ring but has trouble when up against a bigger bully. The Korobov fight is a good example, Korobov went after him fire for fire and won the battle. He does have a good chin but is not overly active in punches thrown.
Plant is 17-0 with 10 KO’s. He’s 26 years old and a a safety-first fighter. He’s faced weak opposition and he sticks to what he’s doing, which is scoring points and getting hit as little as possible in return. He has very quick hands and great head movement and likes to pose and showboat. He tends to lung in when he throws which leaves his head exposed to counters. He has very little foot movement, likes to “fight in the pocket” and vulnerable to be countered.
Plant’s plan will surely be to use speed and movement, hitting and getting out. Except he doesn't get out, he stands in the pocket and avoids punches with head movement. Plant will need to box the best fight of his career to beat Uzcategui. Given Plants lack of foot movement, I don't think he will be able to escape Uzcategui for 12 rounds. I think Plant starts fast builds up points but eventually Uzcategui stops Plant. If you like Plant to win, take him to win by decision.
