The Cowboys are also missing nose tackle Josh Brent, who has been charged with intoxication manslaughter.
"We've gone through a lot of adversity this season with the things that happened," Ware said after Thursday's practice. "It was one of those times where you never know how to take a loss on the team but a lot of guys are staying strong and getting ready for this week. We still got to get out there and play. It lets us know you never know what will happen in life and you have to take advantage of the opportunities that you have."
A report in the Dallas Morning News said Brent had a blood alcohol level of more than twice the legal limit at the time of the crash. The Dallas Morning News reported Brent's blood alcohol limit was 0.18.
With Brent intoxicated it raised questions among the Cowboys' players about what to do if confronted with a situation where they couldn't drive a car after a night of drinking.
"We talk about it all the time," Ware said. "The NFL (has) a thing you can call (to get a car service). There are taxi services around town, even if you have no money to pay."
