Cuboid bone popping out and in? Is that even possible without ligament damage?
"Salazar feared Rupp could have suffered a stress fracture, but changed his mind after Rupp pointed to the area of his left foot that hurt. “I thought it was his cuboid bone, and that was confirmed by our physiotherapist Sean Pena,” Salazar said. Pena judged that the bone had simply popped out of place, and performed an adjustment on it. "
It should also be noted that their Physio is the same guy who worked with Chris Wexstein, who was Justin Gatlin's physio. And is also Tyson Gay's and Kelly ANn Baptiste's.
