Fargas is expected to share time with Zack Crockett at running back in place of starter LaMont Jordan. Jordan, who became the first Oakland running back to rush for 1,000 yards since 2000, is nursing a turf toe injury that kept him out of last week's loss to Denver and has not practiced this week.
Speaking to reporters earlier this week Jordan essentially ruled himself out of the Giants game, thrusting the seldom-used Fargas into the spotlight for the first time this season after Crockett handled the bulk of the load against the Broncos.
''I'd like to get to where we can keep the ball a little bit, get (the Giants) off the field and mix both those guys and get them a good share of carries,'' Oakland head coach Norv Turner said on Wednesday.
Grove, meanwhile, has not fully recovered from his knee injury and would only be available to play against New York in case of an emergency.
''He's limited and I would think his role would be similar to what it was last week,'' Turner said. ''He's not ready to go but he's not that far away. Obviously last week we worked him out Sunday morning and thought he'd be ready to play.''
No Jordan and a limited Grove would be only a few of the changes the Raiders might be willing to make in the season-finale.
''I think each week you try to get yourself an opportunity to do some different things, some different wrinkles,'' Turner said. ''One of the things with us, when you start getting some young guys playing who haven't played a lot you have to make sure the things you do are things they're comfortable doing, and you can't change a great deal. The younger you are, the more base you need to be so you give them a chance to do things without making mistakes.''
