This certainly puts a damper on the opening preseason Chicago Bears victory in front of the home crowd at Soldier Field.

Just when many Bears' fans were reflecting on the win against the Miami Dolphins, Brad Biggs tweets out some bad news.

No sign of #Bears WR Alshon Jeffery and I'm told he was in a walking boot before the game. We will see if John Fox gives details. — Brad Biggs (@BradBiggs) August 14, 2015





When head coach John Fox met the media after the game he revealed that Jeffery strained his calf at practice and is "day to day." The walking boot and crutches could just be precautionary, but with the secretive way the Bears now talk about injuries, it's anybody's guess.

Jeffery will get treatment in Bourbonnais when the Bears head back to training camp, but his status for the joint practices against the Indianapolis Colts next week is in doubt.
