ALAMEDA -- Right guard Mike Brisiel has passed all tests necessary to be available to start against the Jacksonville Jaguars on Sunday.

Brisiel was cleared by the medical staff and had limited participation in a padded practice Wednesday. In cases of previous concussions to Jon Condo and Brandon Myers, the players did little more than run around as part of the process to be cleared.

"I did what I was supposed to do, and they allowed me to practice so I'm not going to miss any time," Brisiel said.

Brisiel remembers little of what happened other than attempting to make a block on a screen pass to running back Mike Goodson that covered 37 yards Sunday against Atlanta.

"I went down and cut-blocked a linebacker. He kneed me in the back of the head, and I kind of went bubbly for a second," Brisiel said. Alex Parsons finished the game for Brisiel at right guard.

With center Stefen Wisniewski missing the opener with a calf injury and Khalif Barnes going down in Week 2 with a groin injury, the Raiders have yet to play a full game with all five of the team's projected starters.

Barnes, who underwent what the club called a "procedure" not long after the injury, is still not practicing, with Willie Smith likely starting his third straight game. Smith has struggled the past two games.

"He's getting a crash course, and he's got to learn fast," coach Dennis Allen said of Smith. "We're going to continue to put him out there and let him keep getting better."

  • Linebacker Aaron Curry returned to practice Wednesday for the first time since an organized team activity May 15. He apparently wasn't holding anything back.

    "He was being extra physical today," safety Tyvon Branch said. "That's what we expect of him."

    Curry, placed on the physically unable to perform list with bad knees before the season, does not count on the 53-man roster. The Raiders have 21 days before having to decide whether to put him on the roster, put him on injured reserve or release him.

  • The Raiders have had success with screen passes to Goodson, Darren McFadden and Marcel Reece, and occasionally tight end Myers. Quarterback Carson Palmer credits offensive coordinator Greg Knapp.

    "Coach Knapp is so ingrained in studying all that stuff and really understands when to pick his spots," Palmer said. "A lot of time it's a total shock and he's so good at setting them up. A lot of teams run screens, but the way they're coached and designed here is special."
