Nurshahidah Roslie, Singapore's first professional female boxer, saw her perfect 4-0 record come to a tearful end last night at Singapore Fighting Championships 4.

Watched by an energetic and raucous crowd of about 600 who packed the ringside at the Singapore Foochow Association, the 29-year-old lost to Gentiane Lupi of New Zealand via a technical knockout.

The contest ended 46 seconds into the fifth round of the 10-round World Boxing Association Oceania Female super-featherweight title bout.

The Singaporean was in tears after the bout ended. After she exited the ring, her supporters hugged her.

But she appeared to be in a daze and almost collapsed. She had to be attended by medical staff, eventually being wheeled out of the venue, but not before composing herself and smiling at those around her.

Lupi, who hails from Wellington, gave credit to her vanquished opponent, saying: "I know how Shah feels. It's horrible to lose at home and I've been through that before.

"But I like her style, she stayed forward while other fighters would be running away, she stood firm and was always aggressive and ready to throw the punches."

Her training partner at Juggernaut Fight Club, Tiffany Teo, who was part of her entourage at ringside, added: "It's really painful to see her lose because I know how hard she's been training."

Teo herself had been in action the night before, winning her bout at mixed martial arts outfit One Championship's Defending Honour event.

Nurshahidah's coach Arvind Lalwani was not too worried about the loss.

Lalwani, who also organised the event, said: "It was a test for her, and we know that to be a world champion is not that simple. I'm confident that she will come back stronger."
