TEMPE, Ariz. (AP) _ Cardinals backup quarterback Dave Brown will get extra work in practice in case starter Jake Plummer can't play next weekend against the Giants.

Plummer, who heads a long list of injured Cardinals after Arizona's rough 34-9 loss at Philadelphia, has a sprained left thumb, bruised ribs and a sore back.

Coach Dave McGinnis speculated Plummer would be able to play next Sunday night at home against the Giants.

``He's going to be day-to-day in practice,'' McGinnis said Monday. ``Right now I'm thinking he's going to be OK, but Dave Brown is going to get more snaps this week in practice.''

Plummer might not practice much, especially early in the week.

``I think day to day he will progressively get better,'' McGinnis said. ``The thing about it is it's not good to miss practice. Jake needs to practice like everybody else.''

The offensive line's breakdown against the Eagles mainly was at right guard, where neither Norberto Davidds-Garrido nor Yusuf Scott _ both filling in for injured starter Lester Holmes _ could hold off the Eagles' rush.

The Eagles sacked Plummer five times and Brown three times.

Plummer also was the recipient of a brutal hit from Hugh Douglas as the Arizona quarterback attempted to slide to the turf at the end of a scramble for a first down.

After studying the videotape, McGinnis said it was a clean hit.

``Of course my first instinct was to protect Jake and throw up a red flag,'' McGinnis said, ``but Jake was running. He kind of had an unorthodox slide anyway, to say the least. It wasn't like he was down, then Douglas accordioned him.''

McGinnis couldn't even name all of injured.

``I can't remember them all,'' McGinnis said. ``It's a litany. You can just start going down through it. Everybody's feeling something.''

Linebacker Zach Walz, only recently back from knee surgery, is out with a broken left leg. Defensive tackle Mark Smith hurt his shoulder and had his arm in a sling on Monday.

Other injuries included safety Kwamie Lassiter (knee sprain), offensive tackle L.J. Shelton (sprained ankle) and safety Tommy Lassiter (bruised shin).

Several other players, including Andre Wadsworth, Aeneas Williams, Simeon Rice, David Boston and Frank Sanders, are bothered by an assortment of ailments.

Running back Michael Pittman, who could hardly walk earlier in the week, now has bruised ribs on both sides.

With his team struggling at 3-9 and losing players right and left, McGinnis said he can't mope about the lack of bodies.

``We need to win games and when the time comes to do it, you've got to do it somehow,'' McGinnis said. ``That's what we've got to do. We're going to continue to work. I promise you that.''
