On a night when Brett Favre and Bart Starr came together at Lambeau Field for a special moment, it was the Chicago Bears who crashed the party and pulled off a 17-13 upset over the Green Bay Packers on Thanksgiving.
The Packers (7-4, 4-2 home) have now lost their fourth game in the last five weeks and could potentially fall back in the NFC North standings this weekend with a Minnesota win.
The loss dimly overshadows what was a monumental evening in Green Bay. Favre's No. 4 jersey was officially retired by his former team with an on-field halftime ceremony that featured an appearance by Packers legend Bart Starr.
