A "fit and healthy" teenager was left in a coma after he suddenly collapsed after football training.
Kieran Prescot had just finished a training session with his teammates when he suffered a cardiac arrest.
The 17-year-old, from St Helens, was given CPR before being rushed to Whiston Hospital and put into an induced coma.
Kieran's mother, Sara Jones, 41, told the Liverpool ECHO : "It was a normal day, I'd dropped him off at football training at Sutton Academy.

"The training was due to come to an end and usually he would be one of the first ones out because he normally goes to training for another team afterwards.
"I was with one of the other mums, we parked next to each other in the car park. We were sat in the car because it was quite cold, chatting away as normal.
"She got a phone call from her son, he said Kieran had collapsed and we needed to go over to the pitch but obviously by the time I got there they were doing chest compressions on him.
"It was quite a shock to be honest. I had my 15-year-old daughter with me so she witnessed all of that. It was heartbreaking."
Sara said football coach Ian Morley initially started administering CPR before Craig Milligan from Sutton Leisure Centre took over until an ambulance arrived.
She said she would like to thank everyone who stepped in to help Kieran and helped to save his life, from the staff at Parkdale Sidac Celtic and the leisure centre, to his team mates, manager of the football team Kev Flannery and football coach Alan Leyland.
Sara said: "There were so many people involved, it was a lot of team effort.
"He's been playing football since he was 12. He's very fit and healthy, even the lads on his team were quite shocked.
"He's the fittest one on the team, he doesn't go out drinking, he doesn't smoke, so we would never expect something like that to have happened."
Kieran spent 24 hours in an induced coma at Whiston Hospital before doctors started to bring him around.
Sara said: "When I've spoken to the doctors and staff at the hospital they said he's got an out of rhythm heart beat, I can't remember the exact words they used.
"It's where his heart goes out of rhythm so he's got to have further scans at Broadgreen Hospital."
Sara said: "They might need to put an internal defibrillator in so it will keep his heart beating at a normal rate so if it goes out of sync it will give it a little shock.
"He's conscious but he's still very confused and disorientated. We're all very grateful to everybody that played their part that night to save his life.
"The staff at Whiston Hospital were really good in A&E and in ICU. I'm really grateful for them.
"I think it shows the importance of people knowing how to administer CPR to save that life."
