MGM Grand, Las Vegas - Olympic gold medal winner Ryota Murata (11-0, 8KOs) of Japan demolished George "Comanche Boy" Tahdooanippah in one round.

Murata dropped him with a hard shot to the body. Once Comanche Boy got to his feet, Murata pinned him in the corner and unloaded with numerous hard right hands to the head until the referee jumped in to save Comanche Boy from further damage.

The fight was supposed to be a junior welterweight eliminator, but Ik Yang (18-2-1, 13KOs) was struggling to make the weight limit of 140 earlier this week and the fight with Lenny 'Lenny Z' Zappavigna (35-2, 25KOs) was changed to a catch-weight of 143-pounds.

This was Yang's first fight in over a year, since losing a twelve round decision to Cesar Rene Cuenca in an IBF title fight last July in Macao, China.

Lenny Z was riding a nine fight win streak that spanned back to his TKO defeat at the hands of Ammeth Diaz in 2011.

Yang was controlling the action in the first three rounds, before Lenny Z began landing some big punches in the the fourth. Lenny Za had a cut in the upper right side of his head and he was bleeding pretty bad. Given the location that cut may have come from a clash of heads.

In the sixth round, Lenny Z stunned Yang with a big hook and then pounded him against the ropes with very big punches until the referee jumped in to wave off the fight.
