Geesus people, he got injured. It wasn't on purpose, I really doubt ANYONE in the NFL is seriously trying to go out and purposely injure someone, especially after everything that happened with the Saints(which is bull**** - anyone that supports that should have been banned from football). Those saying the 1st team shouldn't have been out there, when do you play them? Do you sit them on the sidelines the entire preseason so they gain no chemistry in game situations? Injuries happen, it's part of football. We weren't the only team to have someone carted off today.
He's done for the season, which is unfortunate because he really is a great player, and would have opened up our passing game this year, but good teams can bounce back from injury and persevere. I wish Keller the best in recovery.
