As someone who has known Bears fans to be nothing but class acts (ahem) during trips to Soldier Field to watch the Vikings, we are shocked to read this item about the Packers' Nick Collins. From the AP: NFL officials are investigating a confrontation between Packers safety Nick Collins and a fan after Green Bay's 20-17 loss Monday night to the Chicago Bears at Soldier Field.

League spokesman Greg Aiello tells The Associated Press the league is "in the process of reviewing all the facts."

Milwaukee's WITI-TV aired video footage in which Collins is seen yelling at a fan as he left the field. Collins then appears to throw his mouthpiece into the stands.

According to the station's report, Collins said the fan spit on him and used a racial slur. WITI says Collins apologized for "losing his cool."

Collins had a rough game in some ways. With the game tied at 17-17, Collins picked off Chicago quarterback Jay Cutler but the play was nullified by a penalty.

And on an earlier drive, Collins got called for a late hit on Matt Forte after a 15-yard reception.
