IBF light fly kingpin Nonito Donaire heads up to super flyweight tonight at the Hard Rock Casino in Las Vegas, NV, contending for the Interim WBA crown against Panama's Rafael Concepcion.
Donaire, 21-1 (14), is coming off three title defenses of the IBF strap he won by expertly dismantling Aussie bomber Vic Darchinyan two years ago and the Filipino stylist should be able to handle the challenge of Concepcion with equal dexterity.
Concepcion, 13-3 (8), won the Interim WBA super fly title by gunning down previously undefeated AJ Banal a year ago but was stopped in the ninth in his next bout during a slugfest with Mexico's Jorge Arce, losing the interim belt in the process.
The Panama City man regained his footing with an eight rounds points verdict over aging ex-WBO minimumweight boss Kermin Guardia in February but will have to pull off a career best performance if he is to overcome the higher skilled Donaire.
The chief support bout features WBO feather champ Steven Luevano, 36-1-1 (15), meeting the challenge of WBC International beltholder Bernabe Concepcion, 29-1-1 (16), in what should be a good contest.
