Panthers place DB Jeremy Chinn on IR, activate OL Austin Corbett

The Carolina Panthers placed three players, including defensive back Jeremy Chinn, on injured reserve Tuesday and activated right guard Austin Corbett from the physically unable to perform list.

Chinn (quadriceps), outside linebacker Yetur Gross-Matos (hamstring) and tight end Giovanni Ricci (shoulder) will be out at least four weeks after going on the IR.

Corbett has not played in a game since tearing an ACL in the 2022 regular-season finale against the New Orleans Saints. After missing all of training camp and the preseason, he has practiced for the past three weeks. The Panthers (0-6), who are coming off a bye week, have started three different players in his place: Chandler Zavala, Cade Mays and Calvin Throckmorton.

Zavala and Mays also have had to fill in at left guard for starter Brady Christensen, who was lost for the season in Week 1 due to a biceps injury.

Chinn, 25, was injured in Week 6 against the Miami Dolphins. He has 23 tackles, including two for loss, and one pass defended in starting all six games. The second-round pick (64th overall) of the 2020 NFL Draft out of Southern Illinois has spent his entire career with Carolina.

Corbett, 28, joined Carolina in 2022 and started all 17 games. The Cleveland Browns selected him in the second round (33rd overall) in the 2018 draft out of Nevada, and he also played for the Los Angeles Rams (2019-21).

Gross-Matos, 25, appeared in all six games this season and has 14 tackles, including three for loss and 2.5 sacks.

Ricci, 27, has played for Carolina since 2021 and has appeared in five games this season with one reception for 2 yards.

In other moves, the Panthers signed offensive lineman Brett Toth from the Philadelphia Eagles' practice squad, signed linebacker Luiji Vilain from the Minnesota Vikings' practice squad and released offensive lineman Justin McCray from their practice squad.
