US Paralympic T44 athlete Richard Browne Jr suffered broken ribs and concussion following a car crash in Florida.
The 24-year-old, who spoke to Sports Mole back in October, has been advised to rest for the next three weeks.
A statement from his manager Ian Byers read: "Richard is badly shaken up and in a lot of pain at the moment, but he was very lucky.
"Doctors have advised that he should rest for three weeks, which will impact on his winter training and may mean that we have to review his early season race plans.
"However, Richard has overcome far greater adversity in his life and I am confident that he will be in top shape and ready to challenge for a place on the US Olympic team over 200m and to contend for two individual gold medals at the Rio Paralympic Games."
Browne won double gold at last year's IPC World Championships in Doha.
