ALAMEDA -- Stefen Wisniewski said he feels "100 percent" after the right calf strain he suffered in the Raiders' preseason opener on Aug. 13 shut him down until this week.But will he regain his starting gig at center in place of Alex Parsons for Monday night's season opener against San Diego?"I don't know that," said coach Dennis Allen, "but he will be (active) for the game."It's been a trying offseason for Wisniewski, who missed all of the offseason activities recovering from shoulder surgery before the calf injury turned him into a spectator again."Yeah, it's tough standing and watching," he said following Saturday night's practice at O.co Coliseum. "I want to be out there working and I had to miss some reps this camp. Feels good to be back in there working again and I feel like I'm ready to go."But is he ready mentally and physically?"I mean, I'm real close physically," he said. "I'd like to get some more reps to feel a little more comfortable but I'm ready to play at a high level, I think."It's also interesting to note that Wisniewski is also getting reps at left guard, where he played last year as a rookie."I feel pretty good," he said, "pretty good at guard."There have been no announced setbacks in Jacoby Ford's rehab from his sprained left foot, suffered on Aug. 17 in Arizona, but there has also been little, if any, progress.He has not practiced since the Raiders' second exhibition game so it was no surprise that he was ruled out of Monday night's opener."Were a little bit at a standstill with him right now," said coach Dennis Allen. "Were going to keep evaluating him and see where hes at, but hes obviously out this week."I asked Allen if here was a potential for surgery on Ford.Said Allen: "I dont know that."Rookie receiver Juron Criner, meanwhile, said his sore right ankle will not keep him from playing against the Chargers."Im going to play whenever I get put in," he said. "Its not really my call, but Im just going to go in when I get asked to go in."Im definitely fired up about it. Monday night game, under the big lights, Im just ready to go out there and perform and do whats asked of me."And while Denarius Moore and his sore right hamstring made it through a third straight practice without incident, Allen was not ready to proclaim him good to go Monday."I haven't made that decision yet on him," Allen said. "He's questionable for the game. He was out there again practicing today. All those things are good signs."
