The Green Bay Packers fought back from a 13-0 deficit to overcome the Detroit Lions 23-22 in a controversial Monday night thriller, with Mason Crosby kicking a last-gasp field goal to snatch the win.
But Green Bay hit back in the second quarter through a Jamaal Williams touchdown to trail 13-10 at half-time.
A Crosby field goal early in the third quarter made it 13-13, but Detroit responded with two more successful efforts from Prater to take a 19-13 lead heading into the final quarter.
Another Prater field goal, from 54 yards, made it 22-13 with nine minutes left, before Allen Lazard touched down for the Packers, off a 35-yard pass from Aaron Rodgers, with Crosby's kick making it 22-20.
The game ended in controversial circumstances with a hotly-disputed hands-to-the-face penalty awarded in the dying seconds, with Crosby scoring from 23 yards to snatch victory for the Packers.
It was the second disputed penalty of the game, both hands-to-the-face calls against Detroit's Trey Flowers.
The victory leaves Green Bay with five wins from six matches this season, while the Lions are now 2-2-1.
