Leading 27-23 late in the fourth quarter, Zimmer's Vikings surrendered a game-winning drive to the winless Lions.
Quarterback kJared Goff capped off the 14-play, 75-yard march with an 11-yard touchdown pass to Amon-Ra St. Brown with no time remaining.
Minnesota fell to 5-7 with the loss, which is one of several heartbreaking defeats the Vikings have suffered this season. There has been speculation throughout the season about what would happen if Zimmer posted another losing record.
Well, after today's game, many fans and analysts are not even bothering to wait around to find out. They think Zimmer needs to lose his job after his team became the 0-10-1 Lions' first victim in 2021.
In his first seven seasons, Zimmer posted four winning records with three playoff appearances. He led the Vikings to the NFC Championship Game in 2017.
There's no doubt he's had his fair share of high points in Minnesota, but it is fair to wonder if today was the death knell for his tenure.
