Three boys injured when a tree fell at an Earlsfield cricket field have been named.
Lewis Gaston, Aidan Oakley and George Roberts were all injured when the tree fell at Spencer Cricket Club at about 3.45pm on Saturday afternoon.
The trio were waiting at nets on the ground when the tree fell, trapping them, as the club's senior team took on Cheam nearby.
Lewis and George suffered serious head injuries and remain in hospital. Aidan, who injured a leg, has been discharged.
Surrey County Cricket Club said the boys were taking part in a Surrey Inner London under-nines training session when the incident unfolded.
The club said in a statement: "The boys - Aidan Oakley, Lewis Gaston and George Roberts - were all taking part in a Surrey Inner London U9s District training session and were waiting for a turn to bowl in the nets when the accident took place."
Richard Gould, chief executive of the club, said: "Everybody at Surrey CCC wishes the boys a speedy and full recovery.
"We are all a part of the Surrey family and I can speak for everybody when I say we hope they will be able to continue representing and supporting the club in the future."
The club suspended all cricket after the drama thanked those who had sent good wishes.
"We understand that their condition is improving and we hope that they will continue to improve and make a full recovery," the statement said.
"The club would also like to thank all those people from around the world who have sent the boys their best wishes.
"We have been very moved by the messages of support from the wider cricket community, and are passing them on to the boys and their families."
Former England all-rounder Andrew Flintoff was among those who wished the boys well on Twitter.
A spokeswoman for London Ambulance Service said: "We were called at 3.45pm to Fieldview in Earlsfield to reports a tree had fallen on some children.
"We sent the London Air Ambualnce, three ambulance crews, two single responders in cars and two duty officers. Our staff treated three patients, all reported to be nine-year-old boys."
Charlie Masson-Smith, a spokesman for Wandsworth Council, said: "It has been pretty windy in town today and you can have a really healthy tree but if the wind catches in a particular way a healthy tree can be blown over."
