Ricky Carmichael, three-time defending AMA supercross champion, suffered a knee injury while testing Tuesday and will probably miss the entire 2004 supercross season, according to Honda team manager Chuck Miller.
The Havana, Fla., rider was examined Wednesday by Dr. Rick Lyon, an orthopedic surgeon from Lexington, Ky., who diagnosed the injury as a torn knee ligament, which will require surgery after the swelling in the knee subsides.
Carmichael was training on a test track near Corona for the AMA THQ supercross opener Jan. 3 at Edison Field in Anaheim. He was also planning to ride in two world championship events in Europe next month.
"Ricky and the team were prepared and looking forward to defending the supercross title," Miller said. "Now Ricky is anxious to get the surgery taken care of so he can start his training for the national motocross series."
The outdoor motocross season, which Carmichael has won four years in a row, will start May 16 on the Hangtown track, near Sacramento.
