Seems that Davis tweaked his knee while making a tackle on a punt return in the 2nd quarter. He planted and another player came over the top and Vontae landed awkwardly. He "will be fine" the team says.
But he sat out the rest of the game and had ice on his leg for the rest of the night.
...that and a broken hand by Chris Williams are the only injuries sustained *during* the preseason. Matt Roth and the receiver (who re-injured his ACL) were both early in training camp.
