Practice report: No Felix Jones, DeMarcus Ware

IRVING, Texas -- The Cowboys had eight players listed on the first injury report of the week.

Running back Felix Jones (bruised knee), outside linebacker DeMarcus Ware (flu), center Phil Costa (ankle), safety Matt Johnson (hamstring), defensive end Sean Lissemore (ankle) and running back DeMarco Murray (foot) didn't practice Wednesday.

Center Ryan Cook (hamstring) and outside linebacker Anthony Spencer (pectoral) were full participants.

Ware said he expects to practice Thursday.

Jones' absence could be more of a precaution because it's not considered too serious.

Costa, who's wearing a protective boot over his severely swollen right ankle, said his ankle popped back into place after it was dislocated on the field. He said he doesn't need surgery.
