Presidential stupid injury of the day award goes to Juan Manuel Santos of Colombia. Here's the translated excerpts of this story:
Colombia President Juan Manuel Santos suffered a sprained left ankle while playing an informal game of football with the Sub-20 national team, about to play in the Sub-20 South American championships in Peru.
"(On Wednesday) the President went to hand over the national flag to the members of the Colombian team that was about to set off for Peru and while playing with them a bad movement caused a sprained ankle in his left foot," said John Ocampo, Presidential press secretary.
After the injury, he was taken to a nearby hospital where the ankle was immobilized using a special sock and was told he had to use a cane for walking while the injury healed.
