NAPA -- Defensive end Andre Carter politely waved off reporters after a workout with the Raiders on Tuesday and was hoping for the best.

"I've got to stay low-key" said Carter, an unrestricted free agent. "If it works out, God willing ... "

The decision will be made by general manager Reggie McKenzie, who evaluated Carter with members of his personnel staff.

Carter, whom the 49ers drafted No. 7 overall out of Cal in 2001, made his first Pro Bowl last season after recording 10 sacks for the New England Patriots.

However, he suffered a torn quadriceps Dec. 18 and ended the season on injured reserve. His chances of being a Raider will have a lot to do with how the team thinks he has recovered at age 33.

"We're shaking all the bushes and seeing what falls out," coach Dennis Allen said, "and if we feel like we've got something that can help us, we're going to do it."

Carter had 10 or more sacks in three of his past five seasons, tied the Patriots' single-game record with four against the New York Jets last season, and has 76 in his 11-year career with the 49ers, the Washington Redskins and the Patriots.

  • Center Stefen Wisniewski missed practice because of a calf strain, making it more likely Alex Parsons will start against Detroit on Saturday.

    Considering the amount of time Wisniewski has missed this offseason, Parsons could soon be in line to start the season opener.

  • Safety Michael Huff returned to practice after witnessing the birth of his daughter, 6-pound, 2-ounce Madeline Rae Huff.

    Also back were quarterback Matt Leinart (lacerated right index finger) and wide receiver Darrius Heyward-Bey (shoulder).

  • Allen started the Raiders on a regular-season schedule, which included closing practice to the media. In the past, the Raiders didn't close practices until returning to the facility in Alameda.

    The Raiders practice Wednesday and have their final practice in Napa on Thursday.
