Oakland receiver Darrius Heyward-Bey was back to practice Tuesday for the Raiders during a bye-week workout. He missed the Denver game after suffering a concussion against Pittsburgh -- a hit that forced him to stay overnight at a hospital. Barring a setback, Heyward-Bey should be able to play Oct. 14 at Atlanta.
