Less than 24 hours after touching down in Manila, Panamanian fighter Luis Concepcion and his trainer showed up for training at the Peñalosa Boxing Gym in Taguig on Monday.

Knowing that he will be up against a crack foe this Sunday, Concepcion knows he has to go the extra mile if he hopes to shock the sensational and unbeaten Filipino southpaw Kenneth Llover.

While their match at the Winford Resort and Casino is a non-title affair, the scheduled 10-rounder promises to be a slambang showdown between hard-hitters.

Concepcion, packing a 40-11 win-loss record with 29 knockouts, came in with chief trainer Hector Hernandez and they arrived in Manila at 6:30 Sunday night after leaving Panama City via KLM Airlines Friday night.

They had an eight-hour layover at Schipol Airport in the Netherlands before the final push to the Philippines.

Now 39 years of age, Concepcion brings to the ring a wealth of experience being a two-division world champion.

Llover, 22, is a fast-rising puncher who is the reigning Orient-Pacific Boxing Federation (OPBF) bantamweight champion using the Concepcion clash as a buildup for a proposed world title eliminator bout with Landi Ngxeke of South Africa on 12 October in Japan.

Holding a 14-0 mark with nine knockouts, including four in the first round, Llover has logged a total of just two rounds in his last two bouts.

Last December in Osaka, Llover took out Tulio Dekanarudo in just 58 seconds and in Tokyo last March, the Cavite-based banger needed two minutes and 38 seconds in destroying Keita Kurihara to win the OPBF plum.

Peñalosa, who represents Llover, struck a promotional deal for the knockout artist by signing with the Japan-based Kameda Promotions.

If victorious against Concepcion this weekend and should Llover emerges unscathed, expect him to figure in that key title elimination match in Japan in an effort to enhance his chances of securing a title shot.

Currently, Llover is rated No. 8 by the International Boxing Federation a d No. 14 by the World Boxing Council.
