NFL Media Insider Ian Rapoport reported Tuesday that Jeffery is "progressing well" in his recovery from a calf injury and the hope is that the wide receiver will be ready to play on Sunday against the Green Bay Packers.
Jeffery sat out practice on Monday, casting doubt on his Week 1 availability. The Bears have revealed little about the injury, sustained in early August.
A news item we had earlier today didn't contain this much confidence about Jeffery's possible return for Week 1, so this is good news. A key will be the Bears getting Jeffery on the field Wednesday for practice.
