Shepherd (hamstring) has been ruled out for Thursday's game versus the Bears, Tom Silverstein of the Milwaukee Journal Sentinel reports.
After missing all three practices this week, Shepherd's NFL debut will be put on hold. The North Dakota State product had an impressive preseason -- he nabbed eight catches for 68 yards and two scores -- earning his spot on the 53-man roster as a result. Allen Lazard was called up from the practice squad to add depth to the Packers' receiving corps.
