In an explosive opening to the eight-man lightweight tournament, Van Chanvey stopped Bheut Bunthouen in the third round Sunday at the CTN boxing arena. Blasting away with elbows in the third, Van Chanvey opened up a long, deep gash under the right eye of Bheut Bunthouen, then smashed him in the head with a knee, prompting Bheut Bunthouen's corner to throw in the towel.
