Kirkwood reverted to the Panthers' practice squad Monday, per the NFL's transaction log.
Kirkwood was active for third time this season in Week 18, as he filled in for Shi Smith (illness) and Terrace Marshall (foot). He did not record a reception but was targeted once on 10 offensive snaps. Kirkwood ends the campaign with three receptions for 17 yards, his best totals since his rookie season in 2018.
