Friend Rastly Broxson told well-wishers Paul “picked a firework up to get it out of the way of his mate's son,it went off in his hand. He’s a proper hero.
“He’s in a bad way and the next 24hours are a big deal as to how much of his hand can be saved.”
Others called for cops to hunt down whoever was responsible.
Nick Banting wrote on Twitter: “Just read what happened to that poor lad outside Bloomers this afternoon.
“Delighted for the result today, but whoever is responsible should be punished by the police, and banned from Bloomfield Road for life.
His friends have already raised more than £2,000 for him Credit: JustGiving “Absolute cretin and doesn’t deserve any sympathy for being an idiot.
“Nobody should go to a ground and leave with life long injuries. Just reading about it has properly pi**ed me off. I hope he’s named and shamed, and I hope for the love of god he gets sent down for GBH.”
Paul attended the celebrations with his best friend and his teenage son.
His dad Billy Markham, 70, said: “Paul was near the front of the crowd and he saw this firework next to some little kids.
“He was going to kick it away but he decided to pick it up so he could throw it into an empty space.
“As he’s done that, it’s exploded. It’s gone off like a bomb.
“Apparently there was blood absolutely everywhere.
Paul was at the celebrations with his best friend and his teenage son “A woman tied a Blackpool scarf around his hand and then one of his friends who had just done a first aid course took off his belt and used it as a tourniquet.
“They called an ambulance but waited ages so in the end a friend but Paul in the car and took him to hospital.
“I went down and Paul was chatting to the nurses and trying to keep his spirits up.
“Someone then turned up with a plastic bag and said that they’d found his fingers and put them in there with some ice.”
Billy, who employed his son in his roofing company until he started working for himself about ten months ago, said his son was undergoing a three-hour operation on his right hand on Monday.
He said: “He’s right handed so he’s going to have to learn lots of things again and he won’t be able to work as a roofer anymore with one hand.
“I lost some fingers when I was 16 so know what it’s like. I taught myself to write left handed but I was younger so it was easier for me.
“The people who saw what happened said if it wasn’t for Paul those children near to the firework would have been seriously hurt because of the size of the blast.
“I’m just glad we’re talking about fingers and thumbs rather than his face and eyes.
“I just hope the police catch the morons who brought the firework.”
A Lancs Police spokesman said: "Around 1.40pm yesterday a man suffered serious injuries to his hand and arm in Seasiders Way, Blackpool.
“It was reported the man had suffered the injury after trying to move a pyrotechnic device which had been thrown close to a child.
“The man, aged in his 50s, was treated by officers at the scene and later taken to Royal Preston Hospital for further treatment.
“An investigation into the circumstances around the injury is ongoing.
