Details are a bit sketchy, but according to Fox 6 Sports (pic curtesy of them as well) in Milwaukee this is what happened (you can look at all the tweets below).
Nick Collins was spit on by fan and called the “N-Word”. This caused Collins to throw something at the fan, but before it could go any further Donald Driver tackled him to make sure nothing else happened (Driver is a good teammate).
While you can’t be running into the stands and throwing stuff at fans, if the story happened the way it is being reported I have no issues with what Collins did.
Even if Collins went into the stands ala Ron Artest I wouldn’t have any issues with.
Fans pay good money and it is their right as Americans to boo, trash talk, say you suck and etc, but spitting and racial epithets is taking it too far. I am not a violent person, but if someone spits on me I am not just going to walk away.
Collins had an understandable reaction and he should thank Driver for understanding that even if he was within his right to punch the fan in the jaw, that for the greater good of the Packers and for himself it was best he walked away.
I would hope that the Bears organization would find out who the fan is and have his season tickets revoked. There is a big difference between being a fan and being a racist A-hole and there is no need for those type of people to be at NFL Stadiums.
*UPDATE*
The NFL is looking into the incident and Sports By Brooks has identified the fan, if you know who he is, please let us know.
