NFL officials are investigating a confrontation between Green Bay Packers safety Nick Collins and a fan after Monday night's loss to the Chicago Bears. NFL spokesman Greg Aiello told the AP the league is "in the process of reviewing all the facts." Video footage has been released in which Collins is seen yelling at a fan as he left the field. Collins then appears to throw his mouthpiece into the stands. Collins said the fan spit on him and used a racial slur. Collins has apologized for "losing his cool." Source: The Associated Press
