Rodgers was poised to play the first game since sustaining a concussion in the season finale last year. He sat out Green Bay's 28-26 win over Houston last week.

The back ailment means Rodgers will have to wait at least another week to test out the new offense employed by Green Bay first-year coach Matt LaFleur.

DeShone Kizer, Tim Boyle and Manny Wilkins split time at quarterback against Houston.
