Coach Hue Jackson said Monday that there is a “plan” in place as the Raiders move forward without Al Davis, but neither Jackson nor anybody else in the organization is ready to reveal that plan.

Meantime, NFL owners gathered Monday in Houston for two days of regularly scheduled meetings. The Raiders played in Houston on Sunday, but CEO Amy Trask opted to return home with the team rather than stay for the meetings.

In an email Monday night, Trask addressed the matter of future Raiders ownership. “The team is not for sale,” Trask said. “The team will remain in the Davis family.”

Jackson painted a picture of the Raiders riding out the season without any significant changes being made, at least in terms of personnel decisions and on-field matters.

“We’re in a great situation right now because we’ve laid such a good foundation,” Jackson said. “Coach (Davis) had laid such a good foundation with the people that are here, that we’re kind of up and running and moving in that direction already.”

Jackson said he is on board if Davis’ son Mark, the new voice of the organization, feels the need to hire a general manager-type, or whatever else he deems necessary.

Mark Davis was unavailable for comment.

Al Davis said in a 2006 news conference that former Raiders coach John Madden likely would be involved with the transition phase.

“If something happened to (me),” Al Davis said, “I’m sure (Madden) would be someone that Carole

Davis and Mark Davis would call, along with several others who have been Raiders most of their lives and still have a tremendous loyalty to it.”

Madden spoke publicly Monday for the first time since Davis’ passing. He did not address the matter of serving the team in any capacity. He was still coming to grips with the death of the man who hired him to be coach in 1969 and remained a close friend.

“There’s part of you that says, you know that he’s going to die, but there’s another part that says, Al Davis will never die,” Madden said on KCBS radio. “It’s Al Davis. … Then, you hear the call and you say, well, you shouldn’t be shocked. But it was very, very shocking.

“If you really knew him and you were a part of him, he was the most loyal friend or person that you could have. And then there was a lot of people that he didn’t know. Well, of course, he couldn’t be loyal to them. Like I said, Al Davis isn’t for everyone. But if he’s your friend, if you played for him, if you coached for him, he was that guy. And there was no one that could be better at being that guy than Al Davis.”

For nearly 50 years, Davis presided over personnel decisions, the NFL draft, scouting and game-day decisions and strategies.

That now falls to Jackson, who spent countless hours the past two years gleaning what he could from Davis. He said he will consult with Mark Davis from here on.

“I’m never going to do anything alone here,” Jackson said. “We’re a team here. …

“Obviously I know I’m the lead when it comes to football, and I gladly accept that, but nobody’s going to do anything alone here.”

The good news for the Raiders was the return to practice of tight end Kevin Boss on Wednesday, but less certain was the status of three key starters.

Out with a knee strain since the Raiders-49ers game Aug. 20, Boss was on the field catching passes and doing knee bends. He was listed as limited, meaning he didn’t take all the reps.

Boss, who didn’t travel to Denver for Monday night’s game, said his chances were “good” of playing Sunday in Buffalo.

“It’s been a long time, but it’s good to have him out there in a limited capacity, catching balls, running around,” coach Hue Jackson said. “We’ll see where he is as we keep moving forward.”

Those who didn’t practice were wide receiver Jacoby Ford (hamstring), free safety Michael Huff (groin) and defensive tackle Richard Seymour (ribs). Jackson said he expects Seymour back soon but wasn’t specific about Ford or Huff.

Running back Darren McFadden also didn’t practice, most likely taking another day to recover from a 22-carry, 150-yard effort in the 23-20 win over the Broncos.

Still missing were wide receiver Louis Murphy (groin) and safety Mike Mitchell (knee). Murphy said he hoped to be ready for the home opener against the New York Jets on Sept. 25.

The Raiders are 1-0 for the first time since the 2002 season, the last time they played in the Super Bowl. Yet, coach Hue Jackson’s enthusiasm is tempered by the knowledge that he has a lot of work to do before the Raiders become an elite team.

The Raiders committed 15 penalties for 131 yards in their 23-20 win over the Denver Broncos on Monday night, and they managed only 105 yards passing. Working on a short week and traveling cross country Friday adds to the worries.

“I haven’t slept, the (postgame) meal was horrible, I’ve been watching Buffalo, so I don’t feel good right now because (the Bills) beat the team that they played really badly (Kansas City),” Jackson said Tuesday at his weekly news conference. “Right now I’ve got some issues, and I have to address them. It will take me probably until Sunday to feel good again.”

Jackson came away from the Broncos game with plenty to feel good about from his first victory as an NFL coach, aside from the groin injury suffered by free safety Michael Huff and the hamstring injury to wide receiver Jacoby Ford.

The Raiders dominated both lines of scrimmage, Darren McFadden rushed for 150 yards in his first game action this season, and Sebastian Janikowski’s NFL record-tying 63-yard field goal provided the difference at Sports Authority Field at Mile High.

Jackson said he hammered home the point about the need to establish the run and prevent the Broncos from doing likewise.

“Five

sacks and you rush for 190 yards, that’s a pretty good statement on opening day,” Jackson said.

Janikowski provided the exclamation point just before halftime, when he converted from a distance covered by two other players in NFL history — Tom Dempsey and Jason Elam.

“I have had people text me, ‘Coach, there was no emotion on your face,’ ” Jackson said. “What for? I knew the guy was going to make it. … I was thinking what we were going to do at halftime.”

Janikowski drilled a field goal from 70 yards in pregame warm-ups. He informed Jackson that he was comfortable from as far as 65 yards.

“To be honest, I didn’t hit it that good,” Janikowski said after the game. “It barely got over the bar.”

Quarterback Jason Campbell said the Raiders used a conservative approach on the final drive of the half because they knew they didn’t need much to get within Janikowski’s range.

“We see that in practice all the time,” Campbell said after the game. “This guy kicks 65-, 70-yard field goals. We knew if we could set him up on the right hash, his preference, it gives him the opportunity to kick that field goal.”
