In week 7, the Lions hosted the Washington Redskins. After a scoreless first quarter, each team scored only a field goal in the second quarter: first Detroit's Matt Prater from 43 yards, then Washington's Dustin Hopkins from 38 yards, to tie the game at three points apiece at halftime. The only score of the third quarter was a one-yard touchdown run by the Lions' Zach Zenner. The Lions extended their lead in the fourth quarter via a 27-yard field goal from Prater. The Redskins responded with 14 consecutive points on a pair of touchdowns, first with a one-yard pass from Kirk Cousins to Robert Kelley, and next on a 19-yard run by Cousins. This give the Redskins their first lead of the game, 17-13, with just over a minute to go. The Lions took the lead back on the next drive, when Matthew Stafford hit Anquan Boldin for an 18-yard TD with 16 seconds left, to win the game, 20-17.
