The Dallas Cowboys will take their decision on Dak Prescott's availability for Sunday's contest against the Minnesota Vikings to game time, two sources told ESPN's Ed Werder.
"We are little going to take it into tomorrow (night)," one source said.
Officially Prescott is listed as questionable because of a calf strain he suffered on the game-winning touchdown pass in overtime against the New England Patriots on Oct. 17. He did not take any team snaps during the week in the regular practices, but he did take them in all of the walkthroughs.
