The Panthers made most of their moves on Sunday and Monday following their final preseason tune-up, but waited until Tuesday for their final three cuts. Let go were OT Cameron Erving, Mabin, and DT Taylor Stallworth. Also waived or released earlier in the week were QB Jake Luton, RB Camerun Peoples, WR Gary Jennings, WR CJ Saunders, T Larnel Coleman, DL Antwuan Jackson, LB Bumper Pool, S Collin Duncan, S Josh Thomas, CB Rejzohn Wright, K Matthew Wright, RB Spencer Brown, WR Shi Smith, WR Javon Wims, WR Josh Vann, OL Justin McCray, OL Michael Jordan, OL Deonte Brown, OL Sam Tecklenburg, OL JD Direnzo, DL Raequan Williams, OLB Kobe Jones, OLB Eku Leota, OLB Jordan Thomas, ILB Deion Jones, ILB Brandon Smith, ILB Ace Eley, S Eric Rowe, CB Keith Taylor, CB Stantley Thomas-Oliver, CB Herb Miller, CB Mac McCain, and CB Mark Milton.

Tennessee placed rookie CB Caleb Farley on IR on Tuesday, so they were in dire need of help for a secondary unit that has already been torched through the air this season. Mabin figures to add depth to the back half of the Titans' defense. He made four starts and five appearances for the Jaguars in 2020.

Mabin yo-yoed on and off the 53-man roster last season, making nine appearances for the league's worst team. With the Bengals splurging in free agency and in enviable draft position, Mabin will have a tough time cracking the 53-man roster. 

Mabin was signed to the 53-man roster in late September and spent less than two weeks with the club before being subjected to waivers. He'll add depth following Week 9's bye in case Dre Kirkpatrick (knee) and Darqueze Dennard (hamstring) aren't healthy.
