Darrius Heyward-Bey re-injured his right hamstring during Wednesday's practice.
DHB,
who originally suffered the injury in early May, grabbed his hamstring
on an out pattern and let out an "audible groan." He'll be sidelined
until training camp, and the Raiders will have to cross their fingers
and hope it doesn't linger into preseason action.
this is not good. hopefully he can get back in action and stay healthy
