In week 15, the Lions hosted a re-match with their division rival the Minnesota Vikings. Detroit got off to a slow start, as Minnesota scored two touchdowns to take a 14-0 lead by early in the second quarter. Matt Asiata scored first on a 2-yard TD run, and Greg Jennings followed on Minnesota's next possession, catching an 8-yard TD pass from Teddy Bridgewater. Meanwhile, the Lions offense was held without a first down on its first four possessions. The defense helped the Lions narrow the gap by halftime. Glover Quin picked off a Bridgewater pass and returned it to the Vikings 11-yard line. Two plays later, Matthew Stafford hit Golden Tate with a 7-yard TD pass. On Minnesota's next possession, Bridgewater was intercepted again, this time by Darius Slay. That led to a 29-yard Matt Prater field goal, cutting Minnesota's lead to 14-10 at halftime. In the third quarter, the Lions inched closer on a 30-yard Prater field goal, making the score 14-13. It appeared the Vikings would extend their lead when Blair Walsh lined up for a 26-yard field goal try, but Jason Jones partially blocked the kick, and it sailed wide. The Lions went ahead on their next possession when Prater made good on a 33-yard field goal. The final score remained 16-14 Lions, as Minnesota failed to score on its final two possessions. The win gave the Lions a 10-4 record for the first time since 1991 (and only the third time in franchise history, the other being 1970), their fourth consecutive division win (keeping them undefeated in the NFC North), and put them back in first place since Green Bay lost to Buffalo earlier in the day.
