Also missing was Matt Johnson, who has been sidelined with a right-hamstring injury he suffered the same night Ratliff was hurt.

Meanwhile linebacker DeMarcus Ware (hamstring) was limited and cornerback Mike Jenkins (shoulder), who was inactive during the season opener, participated in a full practice along with tight end Jason Witten (spleen).
