And even with the left side of Ikem Ekwonu and Damien Lewis intact, that'll be a new combination of familiar parts.
Corbett, in his eighth NFL season and on his third team, admitted that's a new experience for him.
"Not familiar at all," he said. "A lot of times when you start racking up injuries, you're signing guys off practice squads, right, making trades, kind of doing that thing. And so for pieces just be able to come in here that we've played with many games before. We have many reps together. It's tremendous and it's really just a credit to this front office of getting that done."
The Panthers kept their top nine blockers from last year intact, allowing them to survive as well as you can when you put a Pro Bowler like Robert Hunt on IR in Week 3, and have three others on that list by the end of Week 9 (counting Corbett, who returned, Zavala, who might, and Christensen).
"It's a brutal sport, especially being in the trenches, things happen," Corbett said. "And so to keep the same personnel, keep the same people, keep that communication alive just makes it easy. Unfortunately, we're in this situation of having to move pieces around, and so we're able to step in and just go get it done."
Other than last week's seven-sack outlier, when three linemen were unable to finish (and they nearly had to play a rookie tight end at tackle), the line hadn't given up more than three sacks in a game, and they still rank fifth in the league in rushing.
"It kind of times up well for us to have that help inside and to have Austin Corbett in here to be able to step in for Cade," Canales said. "It feels like we're going to be able to put our best group out there that we can, to give us a chance to win.
"It's a tribute to the guys working themselves to get back, the athletic training staff doing a great job, being smart about it, using all the information that we have at our disposal with the analytics. And also just the physical therapy and all the things that go into it. And then you know the coaches getting these guys prepared in a group that has been working together for a long time. So I do feel a lot of comfort knowing that we have these guys stepping back in who know what to do, know how to do it."
