FILIPINO  Eumir Marcial on Sunday, April 10 (Philippine time) pulled out an epic comeback in his first professional boxing fight under the glare of Las Vegas, but his three knockdowns was a cause of concern for his massive fans here and abroad.

The Olympics bronze medalist Marcial, after hitting the canvas in the opener and twice in the second round, managed to regain his composure and scored a controversial stoppage over the towering American Isiah Hart in fourth of the six-rounder middleweight tussle.

With the Zamboanga native Marcial pummeling his unheralded foe, the referee ruled a standing knockout 47 seconds into the fourth round that drew a protest in vain from the corner of the wobbled but yet unyielding Hart.

"There might be something bad to happen if the referee did not stop it as the American appeared to be groggy. But the three knockdowns especially the first one when Eumir was hit with a crackling right to the jaw was a bit alarming," said former Olympian Roberto Jalnaiz, who is now based in Long Beach, California.

"Eumir has to religiously work hard back in the gym to be strong as suffering from some knockdowns early of one boxer's professional career may not be a good sign. It's a great warning for him that there's still a lot of work and sacrifices to be done," said Jalnaiz.

It was only Marcial's second-straight professional fight win since completely dominating Andrew Whitfield in four rounds in December, 2020 in Los Angeles.

Marcial's Kagay-anon father-in-law Reynaldo Galarpe, who is also a boxing trainer and promoter back home, acknowledged that the Tokyo Olympics fighter has to seriously   develop his defensive arsenal.

"There's no room for complacency in pro-boxing. You cannot afford to lower your guards down and give the opponent an opening to attack," said Galarpe, who was in Marcial's corner.

"There's a great lesson in those knockdowns that Eumir can take to his advantage in his next fights. A sort of baptism of fire that he won't ever forget."

The 26-year-old Marcial was stiff and sloppy right from the get-go, thus allowing Hart to deck him with a right straight that he barely survived.

Marcial lost his timing in attacking Hart in the second frame that saw him stumbling twice again on the floor  after absorbing a right and left counter swings.

The voice of Marcial's wife Princess hollered from the crowd, prodding him to be always 'alert' and just play his natural game entering the third round.

Amusingly, that was all Marcial needed as he found his rhytmn with aggression en route to orchestrating a spirited comeback and withstanding the scare of a lifetime that dropped Hart to 6-3-1 win-loss-draw record, including 4 knockouts.

Netizens from around the globe quickly took to the boxer's Facebook Page in congratulating Marcial along with some piece of advice.

One Alan Palma wrote: "Eumir Marcial you have a big heart of a Pinoy  warrior . Hope to see you improving and taking the big fight in your division.  Well done Eumir."

Another one Carlo Tungol cautioned: "Improve on (your) footwork to be not a  steady target, laterals and head movement plus speed..all in all you have a good heart and tremendous courage..keep on improving...salute!"
