Here is a comprehensive summary of the 2025 Detroit Lions season:

The 2025 Detroit Lions season, the team's 96th in the NFL and fifth under the head coach/general manager tandem of Dan Campbell and Brad Holmes, began with immense hype as the team was entered as Super Bowl favorites. After a strong 7-4 start that left them just one game behind the NFC North-leading Chicago Bears, the Lions suffered a devastating late-season collapse, winning only two of their final six games and missing the playoffs for the first time since 2022. Their elimination was sealed on Christmas Day during a Week 17 loss to the Minnesota Vikings, a game where they committed a season-high six turnovers. The team's year was plagued by significant injuries, retirements, and departures along the offensive line and secondary, leading to several nail-biting defeats (5 of their 8 losses came by a touchdown or less). Key roster moves included trading wide receiver Tim Patrick to the Jacksonville Jaguars for a 2026 sixth-round pick, and the team kicked off its preseason with the Pro Football Hall of Fame Game against the Los Angeles Chargers on July 31. The regular season began with a 27–13 road loss to the Green Bay Packers, though the squad rallied to take a 28–14 halftime lead over the Bears in Week 2.
