CHARLOTTE, N.C. -- Coach Ron Rivera says the Panthers will be without three starters for Sunday's game against the Miami Dolphins, including defensive end Charles Johnson.
Johnson, who has 8 1-2 sacks this season and 21 sacks in his last 23 games, missed his third straight day of practice Friday with a sprained knee suffered in Carolina's win against the New England Patriots Monday night.
Rivera said Friday Mario Addison, Frank Alexander and Wes Horton will split time at Johnson's spot.
Starting right guard Chris Scott will miss his third straight game with a knee injury and starting linebacker Chase Blackburn will miss his second consecutive game with a foot injury. Backup tight end Ben Hartsock (knee) is also out.
Panthers defensive end Greg Hardy returned to practice Friday and is listed as probable.
