Stallworth (hamstring) signed a one-year deal with the Panthers on Thursday, Aaron Wilson of KPRC 2 Houston reports.
Stallworth received an injury settlement with the Texans on May 30 after hurting his hamstring during minicamp. The 27-year-old appeared in seven contests last season for Kansas City and Houston and totaled eight tackles. He'll likely be competing for a depth role on Carolina's defensive front.
