Aspland, chief sports photographer for The Times, was forced to miss the Wimbledon tennis and the World Cup football after suffering a brain haemorrhage, nerve damage and two broken collar bones in a crash in Harpenden, Hertfordshire, on 10 April, reports the newspaper.
Former Wimbledon champion Boris Becker and England cricket captain Alistair Cook have also joined the campaign, which has seen sports stars pose with a ‘#gwsmarc' message, in photos posted on Twitter.
The photographer, who is recovering at home, said the messages have been a ‘massive boost' to his confidence.
Aspland told The Times: ‘I've suffered enormous memory loss from before the accident to about three weeks afterwards.
‘You can cope with broken bones, but a brain injury is unseen and unknown and I'm on a real learning curve.'
