Chicago Bears coach John Fox waited until after the team's preseason debut Thursday night to reveal that No. 1 receiver Alshon Jeffery strained a calf muscle during a recent training camp practice.
Jeffery, who missed the Bears' 27-10 victory over the Miami Dolphins, is on crutches and wearing a walking boot to immobilize the injured part of his body.
"He did it in a practice before we came [back to Chicago]," HC John Fox said. "He'll be day to day."
Fox said he is unsure when Jeffery will receive the necessary medical clearance to practice.
"He'll be back in Bourbonnais because he has to get treatment," Fox said. "But I can't [say when he'll back on the practice field]. I'll keep you posted."
This is a bit concerning but the walking boot may just be a precaution. For now, we'll take Fox at his word that Jeffery is truly 'day to day.'
