The Dallas defense regressed, as did the protection for quarterback Dak Prescott, in a game the Cowboys badly needed to win to maintain any realistic hopes of making the playoffs.
In a 44-30 loss to the Detroit Lions, owner Jerry Jones' team looked much more like the one with a losing record from before the open week than the group that had won three in a row since to get over .500 for the first time.
Pretty much the only hope for the Cowboys (6-6-1) now is to win their four remaining games, starting in prime time on Dec. 14 at home against Minnesota. Even then, they will need help. That's why the NFL's playoff odds for Dallas are at 8%.
''I, too, knew what was at stake about our odds of getting in the playoffs,'' Jones said on his radio show Friday on 105.3 The Fan. ''So can we literally win out? Of course we can win out. Is it going to be hard? Double of course it is, to win out. We've got to look at the very narrow chance that if we get out here and play better than we played last night, yeah, we can be still playing when playoff time comes.''
The Cowboys couldn't get stops when they needed them, letting the Lions score touchdowns on short fields caused by poor kickoff return coverage twice in the fourth quarter after Dallas had made it a one-score game.
Prescott was sacked a season high-tying five times and threw two interceptions, including one on the first play of the second half that the Lions converted into a touchdown for a 27-9 lead.
The star quarterback was pressured into a throw that went backward, resulting in a 16-yard loss.
Twice in the first half, the Cowboys faced second-and-25 or longer, which is part of the reason they settled for three field goals before the break. Dallas converted just one of three trips inside the 20-yard line into touchdowns.
