Shawn Andrews, Shaun O'Hara sitting

EAST RUTHERFORD, N.J. -- The New York Giants will have to wait another week for their injured players to return.

Tackle Shawn Andrews (back) and center Shaun O'Hara (foot) both will miss Sunday's game against Washington, while tackle David Diehl (hip/hamstring) and wide receiver Steve Smith (pectoral) are doubtful for the game.

Wide receiver Hakeem Nicks (leg) and cornerback/returner Will Blackmon (chest) also will miss the division matchup.

Andrews will miss his second straight game with his back injury. He has not practiced in three weeks and spent time in the hospital last week because of the injury.

Giants coach Tom Coughlin said Wednesday that Andrews' injury was more than just muscle, and added Thursday that Andrews is still struggling.

Diehl, the starting left tackle, has missed the past three games with his injury and it appears that he will not play Sunday. Will Beatty is projected to start his second straight game at left tackle.

"[Diehl's] working, we'll see about the ready part, he's working," Coughlin said.

Smith said he is unlikely to play Sunday, which would mark four straight games he has missed, and considers himself "day to day." He said he was told his partially torn pectoral muscle, which he suffered 22 days ago on Nov. 11, usually takes six weeks to heal. He wouldn't speculate on whether he will need three more weeks to recover.

Nicks, who will miss his second straight game, appears to be improving. He was throwing around a football during the portion of practice open to the media Friday and said he will move his running day up from Wednesday to Monday. If things go well, he possibly could begin practicing Wednesday, but he said it's up to the trainers and doctors.

He said he physically and mentally he's ready to go, but first has to get stitches out of his leg, which he hopes will happen Sunday.

It was originally projected that he would return against Philadelphia Dec. 19, but Nicks is aiming to return a week earlier against Minnesota. He made "good progress" at a doctor visit Wednesday night, according to Coughlin.

"It made me feel a little more comfortable with it," Nicks said of the doctor visit. "I'm a pretty fast healer, with a little bit of praying and taking care of my body I think I'll be all right.

With Blackmon out, Darius Reynaud will be the return man.

"[Blackmon] has made progress but not as fast as you would like," Coughlin said.
