The 29-year-old Wormley has experienced a 3-4 system, with six seasons with the Ravens and Steelers.
He had 7.0 sacks for the Steelers in 2021, when he started 14 games. Last season, he suffered a torn ACL in Week 13 and has been working his way back to health.
The 6-foot-5, 300-pounder has the kind of length they need on the line after coming off the initial cut to 53 with just five linemen on the roster. His 80 career games may help because the current backup linemen (Nick Thurman and LaBryan Ray) have 10 between them, including both of them Sunday in Atlanta.
Bootle, originally an undrafted rookie out of Nebraska, spent the past two years with the Chiefs, appearing in seven games as he rose from the practice squad to the active roster and back.
The Panthers also released defensive lineman Taylor Stallworth from the practice squad, leaving a spot open there.
