NAPA More than 1,000 fans packed the bleachers to watch the Raiders' practice Friday.
Practices today and Sunday also will be open to fans who have free tickets that were distributed at various locations last month.
"I thought the fans were great," coach Dennis Allen said. "I thought the players reacted well to it. At the end of the day, this league is what it is because of the fans, so our ability to do something to give back and give them an opportunity to come and check out what we're doing here, there's a lot of excitement around here.
"I thought it was a good situation both for the fans and for us as an organization."
Raiders players signed autographs briefly after practice, and safety Michael Huff enjoyed the crowd.
"I can get used to this," he said. "I wish we could have it every day."
But wide receiver Darrius Heyward-Bey said he tried to stay focused on practice, not the stands.
"I really wasn't paying attention to them," he said. "For me, I've got to do my job. I can't be out there looking at the fans, waving and everything like that. I pretend like they're not there. I'm glad they came out, though."
Burress watch Veteran wide receiver Plaxico Burress, who played for the New York Jets last season, is interested in signing with the Raiders, according to published reports.
The Raiders have an open roster spot, but Allen said he's happy with the wide receivers he has in camp.
"We're going to look at any options that are out there that we think can make us better," Allen said. "Whether or not we make any moves, that's to be determined, but we're not going to rule anything out."
Still out Punter Shane Lechler (knee), cornerback Ron Bartell (hamstring), linebacker Aaron Curry (knee) and defensive tackle Travis Ivey (conditioning) still have not practiced.
Tight end Richard Gordon (hip flexor) is still out since leaving Tuesday's practice early with his injury.
He's back Wide receiver Denarius Moore (hamstring) returned Friday after missing Wednesday's practice. The team had Thursday off.
