The Lions received the second-half kickoff while holding the lead. Neither their possession nor their lead lasted much longer.
Jared Goff threw an interception on a deep pass intended for Josh Reynolds on the third play from scrimmage. It appeared there was a question about whether Trevon Diggs controlled the interception, but it never went to a full booth replay.
The Cowboys needed only seven plays to cover the 82 yards with Ezekiel Elliott hurdling DeShon Elliott for an 18-yard gain and Tony Pollard getting loose up the middle for 28. Dalton Schultz drew a defensive pass interference penalty on Jerry Jacobs to set up first-and-goal from the 1.
Elliott plowed up the middle for the score.
