''I took a few reps in every drill,'' Gallery said. ''I didn't get the all but I'm going to work into it. They're just playing it precautious. Now it's just getting in, getting comfortable, thinking faster and picking up things as I go.''
Gallery has been relegated to working out privately with a trainer for the past five days. In his absence, veteran lineman Chad Slaughter took all of the work with the starting offense. Gallery and Slaughter split time with the offense Sunday, with the plan being to slowly increase Gallery's workload.
''We're just easing him back, giving him a coupe of shots here and there,'' Shell said.
Jordan returned to practice but was somewhat limited, allowing Justin Fargas and Rod Smart to get in time with the starting offense. Crockett (back), Williams (back) and Gibson (sick) all participated in the full practice.
Gallery said he was unsure whether or not he'd be able to play in the Hall of Fame game against Philadelphia on Aug. 6.
''I have no idea,'' Gallery said. ''I would guess we're a week away but that's up for (the coaching staff) to decide. I hope so. I want to get out there and hit somebody else.''
Not all the news was good for the Raiders. Safety Stuart Schweigert, who led the team in interceptions a year ago, had to leave practice due to a tweaked groin.
''They don't think it's too serious,'' Shell said, ''but we'll have to see.''
Tight end James Adkisson also missed practice. He became the fourth Oakland player to be felled by a sickness that seems to be making its way through the Raiders' locker room.
''It's like that bug is kind of slipping around, one at a time,'' Shell said. ''(Trainer Rod Martin) told the team the other night about what to do and what not to do.''
* Owner Al Davis made his first appearance at training camp. Davis used a walker to get around and was also driven around practice in a golf cart. He and Shell spoke at length following practice before Davis was whisked away.
* Wide receiver Jerry Porter might be deeper in Shell's doghouse than first perceived. In Sunday's workout, Porter spent the afternoon working out primarily with Oakland's second-team offense while Randy Moss, Doug Gabriel and Alvis Whitted handled the reps with the first team. Then, when the team was broken down into three divisions to run sprints after practice, Porter finished last in his group each time, coming in at a slower time than even kicker Sebastian Janikowski.
* Play of the day goes to quarterback Aaron Brooks, who made a perfect throw downfield to Whitted for a 50-yard touchdown. The pass was a perfect spiral and went over the head of defensive back Tyrone Poole before landing in Whitted's hands for the score.
