Paris - Lance Armstrong's last ride at the Tour de France has been delayed after his RadioShack team was temporarily barred from starting for wearing an improper jersey.
TV images showed Armstrong and his teammates putting on normal jerseys with their correct race numbers after they tried to wear a black jersey with "28" on the back.
The figure was selected to honour the 28 million people fighting cancer, which Armstrong's Livestrong Foundation focuses on.
The stage start for all riders was temporarily delayed.
Sunday's 102.5km ride for the 20th and final stage from Longjumeau to Paris is largely expected to be ceremonial - with Alberto Contador set to win his third Tour.
