Naoya Inoue remained undefeated after retaining the undisputed super-bantamweight titles with an eighth-round technical knockout of Ramon Cardenas in front of a packed house inside T-Mobile Arena.
Inoue (30-0, 27 KOs), who was knocked down in the second round, played the aggressor for much of the fight by using precision and power to carve his way through Cardenas (26-2), frequently sending the announced 8,474 gathering into a frenzy.
