Colombian champion Sergio Higuita abandoned the Tour de France after banging his head on the ground in a crash early in the 15th stage on Sunday.
EF Education First rider Higuita went down hard 162km from the finish after losing balance when Luxembourg’s Bob Jungels suddenly swerved in front of him.
Higuita crashed again a few kilometres later and he got off his bike with 134km to go. He was conscious and being attended to by race doctors.
Higuita was 16th overall, 26:12 behind overall leader Primoz Roglic of Slovenia.
Two days ago, Frenchman Romain Bardet pulled out of the race due to concussion following a heavy crash after completing the 13th stage.
