CHARLOTTE The Panthers made another roster move to add secondary depth Saturday, and put another offensive lineman on injured reserve.
The team put guardChandler Zavalaon IR for the second time this season, this one because of a calf injury.
Zavala originally went on IR in Week 5 with a knee injury, but was activated and started three more games before leaving Monday's loss to the 49ers.
His second trip to IR this year is the fifth for a Panthers offensive lineman this year.Robert Hunt(torn biceps) andAustin Corbett(MCL) were placed on IR after Week 2, andBrady Christensen(Achilles) in Week 9.
Corbett was activated in Week 7 and has played the last six weeks (starting four), and they're leaving the door open for Hunt to return after the bye week. Players could conceivably return from IR twice, but they'd count both times against the eight-player limit.
They've activated four from IR so far, withLaBryan RayandJalen Cokercoming back, along with Zavala and Corbett.
To fill Zavala's spot on the active roster, they signed cornerbackKalen Kingfrom the practice squad.
King was a seventh-round pick of the Packers in 2024 out of Penn State and spent the year on their practice squad. After he was released this year in cuts to the 53, the Panthers signed him to their practice squad on Aug. 28.
He helps bolster a secondary that lost rookie cornerbackCorey Thorntonfor the season to a broken fibula, andJaycee Hornto a concussion during the 49ers game. Horn has been ruled out this week.
The Panthers also signedRobert Rochelloff the Cowboys practice squad earlier this week, and will also be without suspended safetyTre'von Moehrigthis week against the Rams.
Also Saturday, the Panthers activated guardSaahdiq Charlesand linebackerIsaiah Simmonsfrom the practice squad by standard elevation.
Charles was signed to the practice squad on Oct. 1 when Zavala went on IR for the first time. The LSU product has played 35 games with 18 starts in the league, during stints with Washington and Dallas.
The Panthers are going to start their 10th different line in 13 games this season (withJake Curhanreplacing Zavala at right guard), and Charles will be the eighth active lineman along withNick SamacandYosh Nijman.
Simmons offers an experienced body on defense and special teams. The former No. 8 overall pick in the 2020 draft (one spot afterDerrick Brown) has played in 84 games with 42 starts during his time with the Cardinals, Giants, and Packers.
