[Merged] Davenport has pectoral injury. (Update per Rapoport: suffered a strain, will miss time but expected back "sooner rather than later")

It's not an Achilles tear. You'll know you've ruptured or torn your Achilles if it feels like you got kicked in the lower leg and no one was around.
Years ago my uncle sustained a partial Achilles tear in a softball game and said it felt like he'd been shot.
