On the Panthers.com roster page, you have to scroll down to the very bottom to find Johnson listed under injured reserve/designated for return. Johnson was placed on the list after suffering a hamstring injury in Week 3. He is eligible to return to practice Nov. 10 and can be added back to the roster as early as Nov. 24, which would allow him to play on Thanksgiving against the Dallas Cowboys.
As well as Carolina's defensive line is performing right now, it's exciting to think about the possibilities when the team's sack leader four of the past five seasons returns to action.
