Brandon Jacobs missed a second straight practice Thursday with a knee injury he suffered in the third quarter of Sunday's win in Arizona. Tom Coughlin said the running back wanted to work but that the medical staff insisted on giving him at least one more day of rest to reduce the swelling.

"I feel pretty good," Jacobs said, although he was noncommittal about playing against the Seahawks. "I didn't do much. I'm just waiting for the time when they unleash me."

Jacobs said that in the context of his injury, but he also could want to be "unleashed" in the running game. In four games, he has 38 carries for 116 yards.

The Giants' running attack has not been producing the numbers it would like to.

"It's always a bunch of little things in the running game," Jacobs said. "If this guy would have done this or that and if we would have taken a different cut . . . We are not happy and this team or organization is not happy with where we are rushing. We have to get it better."

Mario 'not benched'

Offensive coordinator Kevin Gilbride said WR Mario Manningham was not benched in the Arizona game even though there were times when it appeared Victor Cruz had moved into his position.

"Just really seeing some things that we wanted to see Victor do, that we thought Victor would do more effectively," Gilbride said.

Giant stepsCoughlin was impressed when he learned about the 4.84-second 40-yard dash injured safety Chad Jones ran in Louisiana on Wednesday. "Wow," Coughlin said. "I'll have to give him a call." Jones, a third-round pick in 2010, nearly lost his leg in a car accident that summer.
