Johnson (hamstring) has been placed on injured reserve/designated to return, ESPN's Adam Caplan reports.

Johnson was already expected to miss multiple games, and he can now officially be ruled out until Week 12. Although it's still a huge loss for the Carolina defense, the Panthers did trade for DE Jared Allen to mitigate the impact of Johnson's absence. Allen's name may carry more weight, but Johnson is the far superior player at this stage in their respective careers.

Johnson (hamstring) has been ruled out of the Panthers' upcoming Week 4 game against the Buccaneers.

Johnson suffered a significant hamstring injury during Sunday's win over the Saints and will consequently miss Carolina's Week 4 contest. While the Panthers' Week 5 bye allows Johnson another week to get healthy, it remains to be seen whether his injury will hamper him beyond the next couple weeks.

Johnson sustained a hamstring injury Sunday against the Saints and could miss "several" weeks, Joe Person of the Charlotte Observer reports.

Johnson left in the second half with only one assisted tackle on the ledger, bringing his season-long line to five tackles (two solo) and one sack. His diagnosis should be known within the the next few days, but Mario Addison and Wes Horton (shoulder) are present to pick up the slack at defensive end in Johnson's stead.

Prior to his exit from Sunday's contest, Johnson -- who entered Week 3's action with four tackles and a sack -- had recorded just one tackle.

Johnson (calf/upper back) will miss the Panthers' preseason finale against the Steelers on Thursday Joseph Person of the Charlotte Observer reports.

Johnson will have missed the entirety of the preseason a year after sitting out the Panthers' final three exhibition games in 2014 and subsequently getting off to a sluggish first month in the regular campaign that saw him held without a sack. The calf and upper back maladies responsible for Johnson's absence this year, both suffered in practice, currently leave his status for to suit for the team's Week 1 tilt against the Jaguars worth monitoring.

Johnson, who has been dealing with a calf injury, said he will definitely be ready for Week 1 against the Jaguars, Steve Reed of the Associated Press reports.

Johnson returned to practice Wednesday, and appears to be on pace to start in the regular season opener at defensive end. It's possible the Panthers will continue to keep him out of preseason action in order to ensure a full recovery from soreness in his calf.

Johnson (calf) returned to practice Wednesday, Joe Person of The Charlotte Observer reports.

Johnson has battled through a sore calf for the last few weeks but his availability Wednesday suggests that he's headed in the right direction for a full recovery by the season opener against the Jaguars on Sept. 13.

Johnson (calf) tried to return to practice Monday, but was carted off the field shortly into the Panthers' session, the Charlotte Observer reports.

Johnson has been out for the past week due to a sore calf that he tried testing Monday to no avail. With seemingly another instance of aggravation, Johnson probably faces some more time on the sidelines, further leaving the Panthers without their best pass rusher.

Johnson sat out Monday's practice due to an ankle injury, The Associated Press reports.

Johnson tweaked his ankle during practice Sunday, so the veteran sitting out Monday's session really comes as no surprise. Panthers' coach Ron Rivera downplayed Johnson's injury, so any practice absence this week shouldn't be much cause for worry.

Johnson registered two sacks during Saturday's playoff win over the Cardinals.

Johnson (illness) is active for Sunday's game in Minnesota.

Johnson battled an upper-respiratory illness to end the week, resulting in absences from drills both Thursday and Friday, but his ability to travel in advance of Sunday's contest demonstrated his improved health. After a slow start to the season -- only three tackles and no sacks in the first four weeks -- his pursuit of the quarterback has been fruitful over the last seven games, during which he's accumulated five sacks. He could ring up another with Teddy Bridgewater, who's been brought down 22 times in eight outings, on the horizon.

Johnson (illness) is traveling with his teammates to Minnesota, David Newton of ESPN.com reports.

While this doesn't guarantee he will be active for Sunday's game against the Vikings, his ability to make the trip indicates Johnson, who's officially questionable, stands a decent chance of suiting up. Johnson missed the team's final two practices of the week with an upper-respiratory illness but coach Ron Rivera said he was still hopeful he would play.

Johnson (personal) is active for Sunday's game against the Falcons.

Johnson missed practice on Thursday and Friday to be with his ill grandmother, but he rejoined the team this weekend and will be in uniform Sunday. He's safe to deploy Sunday against an Atlanta offensive line that has surrendered a lot of sacks to opposing defensive lineman this season.

Johnson (personal) is listed as questionable for Sunday's game against the Panthers but is expected to play, the Associated Press' Steve Reed reports.

Johnson has missed the last two days of practice to be with his ill grandmother, but head coach Ron Rivera hopes that Johnson will return to the team late Friday night or Saturday and be ready to play Sunday. The defensive end has four sacks over the last six weeks.

Johnson (hip) is questionable for Sunday's game against Cincinnati.

Johnson played through his injury a week ago and had a fine game, posting his first sack of the year and forcing a fumble, but he evidently stressed the injury in the process. He logged just one practice this week, and that was a limited showing Friday.
