Not to say death, did it rarely happen that someone got injured on The Amazing Race?
The only injury accident in my memory was that Dave broke his Achilles in S22. (Just discount Claire's watermelon in S17; it was not a big deal lol.)
It was a big deal... for Claire and the baby inside her at that time.
Jokes aside for Amazing Race (US edition), the only injuries apart from Connor I remember was Lance's injury in Season 5, Gretchen in Season 7, and Mel's hypothermia in UB.
25 seasons and only those few injuries. Not a bad record.
