1 - Dez Lewis and Aaron Williams leave practice following collision
In what was supposed to be a low-key practice, the Bills faced a truly scary moment on the field. During a team period on a pass play while both players had their eyes on the ball, wide receiver Dez Lewis and safety Aaron Williams met in a helmet-to-helmet collision.
Fans in attendance sat in stunned silence and several players went down to one knee, some in prayer, as the medical and athletic training staff attended to Lewis and Williams on the ground. A collective sigh of relief came when both players walked off under their own power.
