Injury update: DE Johnson questionable

CHARLOTTE, N.C. -- The Carolina Panthers added sack leader Charles Johnson to the injury report on Saturday with an undisclosed illness.

The defensive end leads the team with 8.5 sacks. If he cannot play in Sunday's 4:05 p.m. ET game against the New York Jets, Mario Addison is the likely replacement.

Johnson missed two games before last Sunday's 31-13 loss to New Orleans with a sprained right knee.

The only player listed as definitely out for Sunday is running back Jonathan Stewart with a slight MCL tear in his right knee.
