Heyward-Bey, the Raiders' leading receiver this season, ran patterns and caught passes from quarterback Carson Palmer during a light non-contact drill and took part in some team drills as well Friday. That was slightly more than he was able to do a day earlier when he worked out for the first time since the injury.
"I feel pretty good," Heyward-Bey said. "They did a good job of taking care of me and making sure I was OK."
Heyward-Bey moved around without limitations and showed no lingering effects from the scary hit in Sunday's win over the Vikings.
Oakland's third-year wide receiver caught a 4-yard pass from Palmer on a crossing route when he was initially hit by cornerback Cedric Griffin. After Griffin spun Heyward-Bey around as he was making the tackle, Henderson came in to help, but his left knee collided with the back of Heyward-Bey's neck, knocking the Raiders player's helmet off in the process.
After wearing a neck brace earlier this week and going through a battery of concussion tests, Heyward-Bey was cleared to practice this week.
That's an encouraging sign for Oakland, which was down to two healthy receivers on its 53-man roster earlier in the week. Now Jackson's team is almost back to full strength.
T.J. Houshmandzadeh also returned to the field after leaving town to be with his wife for the birth of their child. Jacoby Ford is making progress from his left foot injury and is no longer wearing a protective boot. Rookie Denarius Moore is also walking without the use of a protective boot.
Heyward-Bey and Moore are both questionable while Ford is out.
Defensive tackle Richard Seymour (knee) also practiced for the first time in two weeks, while defensive end Lamarr Houston worked out in full pads after sitting out Wednesday's practice.
