A statement read: 'Cadel Evans will not compete in the men's Individual Time Trial event.
'He has been seen by the cycling doctor, Dr Mark Fisher, and Olympic team Medical Director, Dr Peter Baquie, and they have confirmed he is fatigued and will not recover in time for Wednesday.
'Cycling has advised he will not be replaced with another athlete in that event.
'Michael Rogers will be the only Australian athlete to compete in the men's Individual Time Trial.'
Switzerland's Fabian Cancellara, the defending champion, crashed during the Road Race and rates his chances as 50-50 for the event, in which Tour winner Bradley Wiggins of Great Britain will start among the favourites.
