ALAMEDA, Calif. – Starting Oakland Raiders defensive end LaMarr Woodley is not practicing Wednesday.

Woodley was hurt Sunday in a loss to Arizona. On Monday, interim Oakland coach Tony Sparano wouldn’t disclose the ailment. By NFL rules, the Raiders must identify Woodley’s injury after practice Wednesday.

Cornerback Carlos Rogers watched practice. He has sat out several practices this season.

Three players who missed Sunday’s game did return to practice. Defensive end Justin Tuck (knee), fullback Marcel Reece (quad), right tackle Khalif Barnes (quad) and receiver Vincent Brown (hamstring) are all practicing Wednesday. Barnes and Brown missed the past two games. Even with Barnes back, Menelik Watson could still start. The second-year player performed well in Barnes’ absence.

Meanwhile, Cleveland Browns coach Mike Pettine, in a conference call with Bay Area media, said the Raiders have taken Sparano’s personality since he took over earlier this month.

“I think a lot of Tony and just kind of his approach to football and the mentality,” said Pettine, who worked with Sparano when both were on the New York Jets staff. “It’s clear to see in the games that he’s been in charge that it’s definitely his stamp.”
