Oakland WR Darrius Heyward-Bey was a full participant in practice for the third straight day Friday, and he's expected to return to the starting lineup Sunday at Atlanta after missing a game with a concussion. Heyward-Bey was knocked out in the end zone on a helmet-to-helmet hit by Steelers S Ryan Mundy on Sept. 23. He spent that night in the hospital and missed the Denver game. Heyward-Bey, who was listed as probable for Atlanta, has looked sharp in practice and has suffered no setbacks, but the true test will come Sunday when he takes a real hit for the first time since Mundy KO'd him. "I'm not really worried," Heyward-Bey said. "Everybody who plays football wants to get that first hit in, and you go from there. When it happens, it happens, and you move on to the next play."
