OL Adams out with injured calf
He did not return during the Cowboys' 34-3 season-ending loss.
Doug Free replaced Adams in the lineup.
The turnover resulted in a 23-yard field goal by Ryan Longwell to give the Vikings a 17-3 lead.
Free started seven games in place of injured Marc Colombo at right tackle this season and allowed just one sack in those games.
