Locke (foot) was activated from injured reserve Saturday, but he's still listed as questionable for Sunday's game against the Cardinals.
Locke has missed the Cowboys' last five games while tending to a right foot injury. Even though he's still tagged as questionable, his activation from IR indicates that he's tracking toward being available for Sunday's contest. The potential return of Locke would give the Cowboys another contributor on special teams and added depth in the secondary.
