Dorticos KO's coach in training camp

As cruiserweight Yunier Dorticos gets ready for his Feb. 3 semifinals round in the World Boxing Super Series', he works on some of his counterpunching techniques during training camp.

Things appear to be progressing pretty well on that front, especially considering Dorticos couldn't keep himself from icing his trainer with a counter left hook on the chin.

Have a look...

Dorticos caught his trainer right on the button, instead of the the mitt pad where intended. Pretty brutal.

The undefeated Dorticos (22-0, 21 KOs) will surely want to bring that speed and accuracy to the ring with him in a few more weeks when he take on another undefeated cruiserweight in Murat Gassiev (25-0, 18 KOs), with a shot at the Muhammad Ali trophy — and some big prize money — on the line.

The Cuban will be fighting in hostile territory, Adler, Russia, so some fight ending power could come in handy.
