My thoughts and Prayers are with AJ and his family first and foremost.
As to the football side of the equation, I was looking forward to him matching up with Champ. But, under the heading of silver lining in every cloud, if AJ isn't playing, he can't get injured, it keeps his legs fresher, and it gives guys like Thomas and Starling more time to shine. It will also force Carr into finding the open man, instead of going to his fallback man in AJ. All in all, from a football standpoint ONLY, AJ not being there, could be a blessing in disguise, considering we are in pre-season.
