Source: Steve Smith expected to sit

New York Giants wide receiver Steve Smith, whom the team hoped could return for Sunday's game against Washington, is not expected to play due to his torn pectoral muscle, a source close to Smith told ESPN NFL Insider Adam Schefter on Tuesday.

Smith would like to play next week against the Minnesota Vikings, but playing against the Philadelphia Eagles the week after might be more realistic, according to the source.

Smith, who had 47 catches for 517 yards and three touchdowns this season, suffered the injury during practice in mid-November. At the time, Smith said he was hurt making a catch in an awkward position.

The Giants (7-4) are tied for first atop the NFC East with the Eagles after snapping a two-game slide with their win over the Jacksonville Jaguars on Sunday.

Smith is just one of several key offensive players the Giants are missing.

Eli Manning will also be without top wideout Hakeem Nicks for at least another two weeks after he underwent a procedure to relieve swelling in his leg over a week ago. The Giants will start Mario Manningham and Derek Hagan as their top two receivers against Washington.

Michael Clayton, who was signed last week, will likely see more playing time as the third wide receiver after another week to learn the playbook. And the Giants will try to get Devin Thomas acclimated this week after the wideout was awarded to the team off waivers from Carolina last week.

If Thomas can grasp the offense, he could potentially play against the Redskins, who drafted him in the second round in 2008. He also is an option in the return game as well.

Manning's offensive line has also been decimated by injuries.

Tackle David Diehl (hip/hamstring) told ESPN 1050 radio that he has started running and is feeling better with each day and could start doing individual work this week. Diehl has missed three straight games.

Center Shaun O'Hara has been working hard to return soon as well from a foot injury.

Left tackle Shawn Andrews missed last Sunday's game with a back injury and coach Tom Coughlin said the team is waiting to see how his surgically-repaired back will hold up this week.
