Ware missed practice all week, but the Cowboys listed him as probable for the game.
Ware on Friday said that he'll wear a brace on the shoulder, something he didn't do during last week's overtime loss to New Orleans.
Also, inside linebacker Ernie Sims is listed as questionable on the injury report despite being a full participant. Sims must pass a contact test either Saturday or Sunday in order to play. Sims suffered a concussion in a victory over Pittsburgh two weeks ago, then suffered dizzy spells in the first half of the Saints game.
Sims passed all the written and oral tests last week but didn't take a contact test.
"You live and you learn," Sims said when asked why didn't he take a contact test.
"I don't want to put the team in a bad situation," Sims said after Friday's practice. "I feel good, like I did last week."
Victor Butler was limited in practice with a groin injury but was also listed as probable.
Rookie safety Matt Johnson, who is on the reserve/injured returnable list, was eligible to practice Friday but didn't. Johnson said he'll practice next week, if the Cowboys season is ongoing.
If Dallas wins Sunday night at Washington, it clinches a playoff berth.
