1. Brett Favre – 2010
The Minnesota Vikings welcomed the Chicago Bears to Minneapolis in Week 15. One of the biggest surprises of the day was the fact that veteran QB Favre started but he didn’t stay on the field for long. He was a late inclusion after missing the week’s practice sessions because of a sprained shoulder. Furthermore, he even played well in the first quarter with one touchdown pass. But then Corey Wooton slammed him on the ground.
Favre smacked his head off the frozen solid ground and lay motionless for a few seconds. In sum, the Bears ended his career then and there. Then, to rub salt into his wounds, Chicago built on their lead, crushing the Vikings 40-14. You couldn’t have scripted a worse ending for one of the game’s legends. The concussed great’s team lost and he suffered a knockout blow on a miserable December day.
