King's Lynn speedway star Lewis Kerr is out of a coma after a crash on Sunday left him with critical injuries.
The 25-year-old, who rides for the King's Lynn Stars, was competing for his lower-level side, Newcastle, in the Premier League Fours event at Peterborough on Sunday when he was involved in a collision and hit a fence.
His wife Jessie Kerr wrote on Facebook on Wednesday morning: 'Lewi is out of an induced coma and is breathing for himself now and remains in critical care. This is amazing and although it's early days and we are not out of the woods by any means, it's a positive.'
'Myself and Family can't even begin to explain what the support has meant these last few days. Every message, picture, donation has given us strength during the worst time of our lives, so thank you all from the bottom of my heart.'
A fund for the family had reached almost £4,000 by Wednesday morning.
The Heacham-based racer was airlifted to Addenbrooke's Hospital in Cambridge, after sustaining severe head injuries in the incident, which was witnessed by his parents and his wife Jessie.
His family is by the bedside at Addenbrooke's where he remains in a medically-induced coma.
