The New York Giants have officially ruled out Brandon Jacobs playing against the Dallas Cowboys this week.

Giants running back Brandon Jacobs has been declared out of the Giants game Sunday night in Dallas.

Tom Coughlin made that announcement moments ago after Jacobs missed his third straight practice with an injured left knee.

“We just didn’t feel like hed be ready to play,” Coughlin said.

Derrick Ward will start in place of Jacobs. Asked if that meant Ahmad Bradshaw would get a little more work than usual, Coughlin said “Well see how the game goes.”

LB Jonathan Goff (hamstring) has also been ruled out and DT Fred Robbins (shoulder) will be listed as “questionable”.

The Cowboys’ defense has played better of late, but they’re still just average at best against the run. I wouldn’t trust Ward and Bradshaw to light up the fantasy scoreboard this week, although neither would necessarily be a bad start.

Here are a few fantasy observations from Thursday night’s game…

1. Clinton Portis was not involved in Washington’s passing game. He was targeted on one pass, which he caught, but it was negated by a penalty. For a player that caught 47 passes last year (that’s almost three a game), this is pretty worrisome, especially for Portis owners in PPR leagues. 84 yards on 23 carries isn’t great (3.7 ypc), but at least we don’t have to worry about him not getting enough touches. It’s clear that he’s the centerpiece of the offense, even to a fault.

2. Chris Cooley was targeted twice. He had an 18-yard gain negated by a penalty, so he didn’t get his first official catch until late in the second half. Jason Campbell spent most of his time looking to Santana Moss (5-37-1) and Antwaan Randle El (7-73). No other player caught more than a single pass. It’s important to note that Cooley has had poor games in each of the last three seasons, and he’s bounced back each time.

3. The Redskins’ new West Coast Offense looks rough. The running game is okay, but Portis was behind the eight ball a little bit because the Giants were daring Washington to throw the ball. The Redskins’ season depends mainly on how quickly they can learn and execute the WCO. In fairness, they faced a tough Giants defense in an emotional road game, and they should fare better in their next two games, which are against the Saints and Cardinals (and are both at home).

4. Eli Manning is still erratic. He seemed to hook up with Plaxico Burress (10-133) at will, but he didn’t throw for a score (though he did run for one), had one pass picked off and had three or four more that were almost intercepted. Eli is a bit of a gambler, and it doesn’t look like a Super Bowl win has changed that at all.

5. Derrick Ward is Brandon Jacobs’ backup. There has been a lot of talk about a “Thunder and Lightning” combo with Jacobs and Ahmad Bradshaw, but Bradshaw didn’t get a carry in the game. Ward carried the ball nine times and had two catches, so he’s the better handcuff for Jacobs.

6. Both defenses looked pretty solid. Admirable job by the Redskins to hold a pretty good Giants offense to 16 points despite getting no help from their offense. The Giants flew around the ball and seemed to pressure Campbell on just about every play. The injuries at DE are a concern, but the Giants DT looks good as a whole.
