Moore (groin) was an active participant at the Cowboys' training camp practice Thursday, Tommy Yarrish of the team's official site reports.
Moore was sidelined with a groin injury throughout the past week, but he was able to work back into practice Thursday. The cornerback was selected in the fourth round of this year's draft, and he now appears likely to make his debut with Dallas on Saturday against the Seahawks in the team's preseason opener.
