While Jones worked on the side during practice, he wasn't involved in any work on the field with the rest of the team for the second day in a row.
"It seems like he's getting better," said Cowboys coach Jason Garrett, who added that Jones had been in all offensive meetings. "We just felt it was the right thing to do today to not practice, and obviously keep him engaged with our team, and hopefully he'll get some work here in the next couple of days."
Rookie running backs DeMarco Murray, the team's leading rusher with 897 yards, and Phillip Tanner already are on season-ending injured reserve. That leaves Sammy Morris, a 12-year veteran who made his season debut at Tampa Bay after signing with Dallas last week, and Chauncey Washington, who was signed to the practice squad Nov. 30.
Morris and Washington again split time at practice Wednesday.
"I'm hoping to see what he can do either today, tomorrow," Cowboys running backs coach Skip Peete said of Jones. "At the end of the week, obviously we've got to be able to see him be able to do some things to make a decision on whether or not he can play in the game or not."
