Panthers’ Derrick Brown Dealing With Knee Soreness As Carolina’s Defensive Front Piles Up Injuries

Derrick Brown has missed practice time off and on for two weeks now, and it’s starting to look less like routine veteran maintenance and more like a situation worth watching closely.

The Carolina Panthers’ Pro Bowl defensive tackle sat out Tuesday’s session with knee soreness, was held out again for what head coach Dave Canales called a scheduled “veteran day” around a scrimmage in late July, and was listed as a limited participant in Sunday’s practice, according to Joe Person of The Athletic. Brown has been able to work through the discomfort rather than sit out entirely, but Canales made clear this week the team isn’t rushing him.

“We sat him out on Tuesday to see if we can get him to rebound,” Canales told reporters, per Panthers Wire. “It’s still pretty sore. So I don’t wanna put him back out with the full group until he feels ready to go back in there. He had a great session on the grass today. Ran around, did some stuff inside. So, he’s trending in the right direction with the guys. We’ll just keep tabs on that on when we can roll him back into practice.”

Why Brown’s Knee Is Being Watched So Closely

The caution makes sense given recent history. Brown tore his meniscus in Week 1 of the 2024 season and didn’t play another snap that year. He came back in 2025 and had arguably the best season of his career — a career-high 5.0 sacks, 73 tackles and a 13-tackle outing in Week 18 that was the most by any defensive lineman in the league that week, per Alex Zietlow of the Charlotte Observer. That bounce-back is exactly why Carolina isn’t taking chances with soreness in the same knee now, even if this is officially unrelated swelling and not a structural issue.

Brown has been the anchor of this defensive front since Carolina made him the seventh overall pick in 2020, and his value shows up more in what he prevents than what he accumulates. A 320-pound presence who commands double teams up the middle changes what an opposing offense can do in the run game, even on snaps where his name never shows up in the box score.

Scourton’s Season-Ending Injury Adds to the Concern

Brown’s knee is the second serious injury blow to Carolina’s defensive front this camp. Outside linebacker Nic Scourton tore his ACL on the very first day of padded work, carted off the field in what teammates described as an emotional scene. Tight end Tommy Tremble later said, via Joe Person of The Athletic, “It was really just unfortunate for Nic… It kind of sucked the life out of us when we saw it happen.”

Because the injury happened inside the CBA’s mandatory five-day, no-contact acclimation period, the NFLPA opened an investigation into whether the Panthers violated the rules governing early camp work. That investigation has since concluded, with NBC Sports reporting the union found no wrongdoing by the team and determined it was simply an unfortunate on-field accident.

Scourton, a second-round pick out of Texas A&M in 2025, tied for the team lead with 5.0 sacks as a rookie and was expected to start opposite big-money free-agent addition Jaelan Phillips. His loss pushes Princely Umanmielen and Patrick Jones II into larger roles on the edge — but it’s a separate injury from Brown’s, on a different level of the defense, which is part of why the timing stings. Carolina is trying to replace an interior anchor’s snaps with soreness management at the same time it’s replacing an edge starter for the entire year.

What’s Next for Carolina’s Front Seven

None of this is happening in isolation, either. Carolina is also already managing a extended absence for starting right tackle Taylor Moton and working without left tackle Ikem Ekwonu, who tore a patellar tendon in January, per Yahoo Sports. That’s a defense and offensive front both absorbing real hits before the preseason has finished — which raises the stakes on Brown’s health specifically, since he’s the one player in that group who’s both irreplaceable statistically and has a recent history of exactly this kind of injury turning serious.

If Brown’s knee soreness clears up the way Canales is describing — gradual, trending in the right direction, no setback — the Panthers still have their best interior piece for a defense that needs to be tougher against the run than it was during last season’s play-in finish to the playoffs. If it lingers into the regular season, Carolina’s margin for error in the NFC South gets a lot thinner. For now, this is a monitored situation, not a crisis — but it’s one worth checking again once padded practices ramp up and Carolina plays its next preseason game.
