The Blackhall youngster was guest of honour at the Black Cats' final home game of the season against Swansea City today.
Bradley, who is battling childhood cancer neuroblastoma, was carried onto the Stadium of Light pitch by 'best friend' Jermain Defoe before the game to a rapturous reception from fans both home and away.
Parents Gemma and Carl had initially feared Bradley - who turns six later this month - would be in too much pain to attend today's match or that they might have to leave early, but he was determined not to miss out.
"He was in a lot of pain but he had said he enjoyed it and had had a lovely day," said Gemma.
The family were guests of SAFC owner Ellis Short and chief executive Martin Bain in the Stadium of Light directors' box: "He had fun kissing all the girls and getting lots of cuddles," said Gemma.
"Then he went down to the Montgomery Suite and made the Man of the Match presentation to Jermain. He even got to say a few words."
Stepping out onto the pitch and hearing the response from the stands had been an emotional experience: "The response from the supporters was absolutely fantastic, as usual," she said.
"The Swansea fans, as well, were brilliant.
"It is very overwhelming. We really appreciate the support.
"It is absolutely fantastic and it does make a hard time a lot easier.
"We just wish all the other kids get the same support as Bradley."
