Pro Football Weekly reports that DHB is signed and sealed:

Rookie WR Darrius Heyward-Bey has agreed to terms on a deal with the Raiders and may arrive at training camp in time for practice Thursday, according to reports.

Heyward-Bey, the seventh-overall pick in this year’s draft, was hampered by a hamstring injury throughout OTAs and minicamps, and his health status is unclear, although he was expected to be healthy in time for camp. The Maryland product should contribute immediately as one of QB JaMarcus Russell’s top targets.
