Tour de France Concussion Cases Expose Limits of Roadside Checks

Three riders have abandoned the Tour de France after being diagnosed with concussion only after completing their stages, highlighting gaps in the sport's roadside assessment protocol.

• Eight riders have abandoned the Tour de France since its July 4 start in Barcelona, with three withdrawing due to concussion.
• The three concussed riders — France's Clement Berthet, Dutch rider Alex Molenaar, and Norway's Torstein Traeen — all crashed, finished the stage, and were diagnosed later.
• UCI medical director Xavier Bigard said it is "never very satisfactory" to see riders diagnosed with concussion after they have resumed racing.
• Tour de France chief doctor Florence Pommerie stated she did not see any of the three riders return to the medical car after their crashes.
