Anthony Ogogo made a sensational start to his professional career.

The Lowestoft middleweight produced a thumping right hand to floor Kieron Gray, 35, in the second round in front of an ecstatic crowd at the Motorpoint Arena in Sheffield. Gray just about beat the count, but the referee ruled he was in no fit state to continue.

It was Ogogo's first outing since his magnificent bronze medal-winning performance at the London Olympics last summer.

'That was phenomenal, brilliant,' said the 24-year-old. 'The one frustrating thing is that the referee waved it off because I would happily have done the six rounds tonight,' said Ogogo. 'I really thought I was going to go the six rounds because he is a tough guy – he has only been put down once before in his career.

'It was really enjoyable. I was really nervous. It's the best part of a year since I last boxed. It was nice to be doing what I love doing.

'It was quite daunting boxing without a head guard. I was looking around, thinking 'when are they going to put my head guard on'?'
